The ability to recognize someone’s voice exists on a broad spectrum with phonagnosia on the low end and super recognition at the high end. Yet there is no standardized test to measure an individual’s ability of learning and recognizing newly-learnt voices with samples of speech-like phonetic variability. We have developed the Jena Voice Learning and Memory Test (JVLMT), a 22min-test based on item response theory and applicable across languages. The JVLMT consists of three phases in which participants first become familiarized with eight speakers and then perform a three-alternative forced choice recognition task, using pseudo sentences devoid of semantics. Acoustic (dis)similarity analyses were used to create items with different levels of difficulty. Test scores are based on 22 Rasch-conform items. Items were selected based on 232 and validated based on 454 participants in an online study. Mean accuracy is 0.51 with an SD of .18. The JVLMT showed high and moderate correlations with the convergent validation tests (Bangor Voice Matching Test; Glasgow Voice Memory Test, respectively) and a weak correlation with the discriminant validation test (Digit Span). Empirical (marginal) reliability is 0.66. Four participants with super recognition abilities and 7 participants with phonagnosia were identified (at least 2 SDs above or below the mean, respectively).The JVLMT is a promising diagnostic tool to screen for voice recognition abilities in a scientific and neuropsychological context.

AbstractListening to autobiographically-salient music (i.e., music evoking personal memories from the past), and transcranial direct current stimulation (tDCS) have each been suggested to temporarily improve older adults’ subsequent performance on memory tasks. Limited research has investigated the effects of combining both tDCS and music listening together on cognition. The present study examined whether anodal tDCS stimulation over the left dorsolateral prefrontal cortex (2 mA, 20 min) with concurrent listening to autobiographically-salient music amplified subsequent changes in working memory and recognition memory in older adults than either tDCS or music listening alone. In a randomized sham-controlled crossover study, 14 healthy older adults (64–81 years) participated in three neurostimulation conditions: tDCS with music listening (tDCS + Music), tDCS in silence (tDCS-only), or sham-tDCS with music listening (Sham + Music), each separated by at least a week. Working memory was assessed pre- and post-stimulation using a digit span task, and recognition memory was assessed post-stimulation using an auditory word recognition task (WRT) during which electroencephalography (EEG) was recorded. Performance on the backwards digit span showed improvement in tDCS + Music, but not in tDCS-only or Sham + Music conditions. Although no differences in behavioural performance were observed in the auditory WRT, changes in neural correlates underlying recognition memory were observed following tDCS + Music compared to Sham + Music. Findings suggest listening to autobiographically-salient music may amplify the effects of tDCS for working memory, and highlight the potential utility of neurostimulation combined with personalized music to improve cognitive performance in the aging population.

Abstract Background Working memory (WM) abilities are frequently impaired in neurological disorders affecting fronto-parietal cortical/sub-cortical structures. WM deficits negatively influence interventional outcomes and everyday functioning. This study thus aimed at the following: (a) developing and standardizing an ecologically valid task for WM assessment ( Ice Cream Test, ICT); (b) validating and norming a novel WM test (Digit Ordering Test, DOT), as well as providing updated norms for digit span (DS) tasks, in an Italian population sample; (c) introducing a novel scoring procedure for measuring WM. Methods One-hundred and sixty-eight Italian healthy participants—73 male, 95 females; age: 48.4 ± 19.1 (18–86); education: 12.1 ± 4.8 (4–21)—underwent a thorough WM assessment—DOT, ICT, and both forward and backward DS tasks (FDS, BDS). The ICT requires participants to act as waiters who have to keep track of customers’ orders. For each task, WM and total (T) outcomes were computed, i.e., the number of elements in the longest sequence and that of recalled sequences, respectively. Norms were derived via the equivalent score (ES) method. Results DS ratios (DSRs) were computed for both WM/S and T outcomes on raw DS measures (BDS divided by FDS). Age and education significantly predicted all WM tasks; sex affected FDS and DSR-T scores (males > females). WM measures were highly internally related. Discussion The present work provides Italian practitioners with a normatively updated, multi-component, adaptive battery for WM assessment (WoMAB) as well as with novel outcomes which capture different WM facets—WM capacity and attentive monitoring abilities.

BACKGROUND: Mastication improves cognitive function by activating cerebral cortical activity, and it is important to demonstrate the cognitive effects of masticatory training using a variety of different interventions. OBJECTIVE: This study aimed to evaluate the effects of masticatory exercise on cognitive function in healthy older adults living in the community. METHODS: For six weeks, twelve participants performed a masticatory exercise using a NOSICK exerciser device, and thirteen subjects performed daily life without masticatory exercises. Trail Making Test, Digit Span Test, and Stroop test were used to measure the cognitive function. RESULTS: The participants in the experimental group showed significant improvements in TMT-A/B (p= 0.001 and 0.004), DST-forward (p= 0.001), and ST-word (p= 0.001). The effect sizes after the intervention were calculated as (1.2 and 0.8) for TMT-A/B, (0.8 and 0.2) for Digit Span Test forward/backward, and (0.6 and 0.2) for Stroop test color/word. CONCLUSIONS: We suggest that the masticatory exercises improve cognitive function in healthy older adults. Therefore, masticatory exercises can be used as a therapeutic exercise during cognitive rehabilitation.

Symptom exaggeration and feigned cognitive impairment occur commonly in forensic and medicolegal evaluations. As a result, methods to detect feigned cognitive impairment are an indispensable component of neuropsychological assessments. This study reports the results of two neurophysiological experiments using a forced-choice recognition task built from the stimuli of the Word Memory Test and Medical Symptom Validity Test as well as a new linguistically informed stimulus set. Participant volunteers were instructed either to do their best or to feign cognitive impairment consistent with a mild traumatic brain injury while their brain activity was monitored using event-related potentials (ERP). Experiment 1 varied instructions across individuals, whereas Experiment 2 varied instructions within individuals. The target brain component was a positive deflection indicating stimulus recognition that occurs approximately 300 ms after exposure to a stimulus (i.e., the P300). Multimodal comparison (P300 amplitude to behavioral accuracy) allowed the detection of feigned cognitive impairment. Results indicate that, for correct responses, P300s were equivalent for the simulated malingering and good effort conditions. However, for incorrect responses, feigned impairment produced reliable but significantly reduced P300 amplitudes. Although the P300 is an automatic index of recognition—even when knowledge is hidden—its amplitude appears capable of modulation by feigning strategies. Implications of this finding are discussed for research and clinical applications.

The purpose of this investigation was to examine the efficacy of using the Recognition Memory Test (RMT), Digit Span subtest (WAIS-R), and Knox Cube Test as markers for malingered memory deficits. Participants were 100 subjects from three general populations: university students, federal inmates, and patients with head injuries. Twenty students, 20 inmates, and 20 patients with head injuries resulting in memory impairment were instructed to try their best on the assessment procedures. The remaining 20 students and 20 inmates were instructed to malinger memory impairment on the procedures. The experimental-malingerers (i.e., students and inmates) performed more poorly than the patients with head injuries on nearly every score derived from the three tests. Discriminant function analyses using the age-corrected Digit Span scale score, the Knox Cube Test total score, and the RMT raw scores for words and faces as predictors of group membership resulted in an overall 98% correct classification rate and 100% correct on cross-validation. Simultaneously applying two empirically-derived RMT cutoff scores resulted in an overall correct classification rate of 100%. The extraordinarily high classification rates in this study were likely influenced by the experimental design and procedures.

Abstract Background: Parkinson’s disease (PD) is the second most common neurode-generative disease, usually detected by its motor symptoms. The non-motor symptoms, including cognitive deficits, have been of great interest to researchers in the last few decades. Aim: To assess the effect of pramipexole on learning and memory in naïve and haloperidol-challenged rats. Materials and methods: Male Wistar rats divided into 9 groups (n=8): naïve - saline, pramipexole 0.5; 1 and 3 mg/kg bw; Haloperidol groups - saline, haloperidol, haloperidol + pramipexole 0.5; 1 and 3 mg/kg bw. Two-way active avoidance test (TWAA) and activity cage were performed. The studied parameters were: number of conditioned and unconditioned responses, vertical and horizontal movements. Statistical analysis was done using SPSS 19. Results: The naïve experimental groups significantly increased the number of conditioned responses during the tests for short- and long-term memory, compared with the saline groups (p<0.05). During the short-memory test only the animals with the lowest dose of PMX significantly increased the number of unconditioned responses whereas during the long-term memory test all experimental groups increased the number of escapes in comparison with the saline groups (p<0.05). Challenge dose of haloperidol attenuates learning and memory in pramipexol treated rats. Only the highest dose of pramipexol showed significant increase in conditioned and unconditioned responses compared with the haloperidol group (p<0.05). Conclusion: Pramipexole improves learning and memory in naïve rats by enhancing dopaminergic neurotransmission. This is probably not the only mechanism involved. This is confirmed by the decrease in learning and memory ability in rats with haloperidol-challenge.

Abstract Objective The Hopkins Verbal Learning Test–Revised (HVLT-R) and Brief Visuospatial Memory Test-Revised (BVMT-R) are memory tests with embedded measures of performance validity (Recognition Discrimination [RD] and Discrimination Index [DI], respectively). We evaluated whether cognitive ability and age influenced embedded measures of effort. Methods Participants included 30 young adults (YA) and 29 older adults (dichotomized into unimpaired [OAu] and impaired [OAi]). Participants completed a medication management ability assessment (MMAA), daily memory lapses survey (DM), digit span, and the Transverse Patterning (TP) and Reversal Learning (RL) computerized tests. Two Repeated-Measures MANOVAs were conducted to determine if Passing PVT and Age/Cognitive Ability influenced performance. An ROC analysis was conducted for HVLT-RD and BVMT-DI to determine pass/fail, and false positives/negatives on embedded measures. Results Those in the YA group who failed RDS (YA-fail), performed better than OAi-fail and OAi-pass groups on RT Errors (p &lt; .0001). On TP Errors, the YA group differed from all four OA groups (p &lt; .0001). On MMAA a significant difference was observed between OAi-fail and all other groups (p &lt; .001). On RD, YA groups differed from both OAi groups (p = .0008). On DI, the YA groups differed from the OAi-fail group (p = .002). A logistic regression classified 43/57 participants successfully into the three cognitive groups using the six predictors (χ2 = 55.73, p &lt; .0001, R2 = .468). RT Errors and TP were significant (Likelihood χ2 = 7.25, p = .027). Conclusion HVLT-RD failed to detect validity for OAi, as did BVMT-DI for YA and OAu. Instead, impairment effects are seen on HVLT-RD and BVMT-DI where YA groups differed from some combination of both/one of the OA groups.

The Impact

Abstract Social identity theory shows that individuals’ social identity can become salient in some contexts and affect their cognition and behavior. Little research has focused on the impact of ethnic identity salience on the group-reference effect in the remembering-knowing recognition task. Thus, the current study aims to examine this effect of ethnic identity salience. In Experiment 1 we recruited 26 Tibetan students and 30 Han Chinese students from a predominantly Han Chinese university. In Experiment 2, we selected 26 Tibetan students and 30 Han Chinese students from a predominantly Tibetan university. Two weeks before the experiment, all participants reported the baseline level of their social identity salience. After two weeks, each participant underwent a memory test. Tibetan students at the predominantly Han Chinese university showed evidence of higher ethnic identity salience and superior recognition memory performance during a Tibetan reference encoding task than during a Han Chinese reference encoding task (Experiment 1). However, Tibetan students at the Tibetan-majority university did not show this effect (Experiment 2). In comparison, Han Chinese participants did not show any social identity salience in the two experiments. The results show that the salient social identity had an effect on the group reference effect in a remembering-recognition memory test. The current study contributes to the past literature by providing a tentative further understanding of the relationship between social identity salience and remembering judgments.

Background. Olfactory identification ability has been associated with processing in the orbitofrontal cortex (OFC), an area that has been implicated in the pathophysiology of obsessive–compulsive disorder (OCD). Although olfactory sensitivity is normal in patients with OCD, no study has investigated olfactory identification in this disorder.Methods. A group of 20 subjects with OCD and 23 age- and education-matched controls performed a standardized test of olfactory identification. They also performed computerized tests of spatial memory span, spatial working memory and spatial recognition memory that have been shown previously to be sensitive to cognitive deficits in patients with OCD.Results. Performance on the olfactory identification task, spatial recognition task and spatial span task was significantly worse in the OCD group than controls.Conclusions. While impairment in spatial cognition is consistent with previous studies of OCD, its significance for brain-behaviour models of OCD is unclear. However, the finding of abnormal olfactory identification in patients with OCD is consistent with the hypothesis that there is a disruption to processing at the level of the OFC in the disorder.
