Starting Tests With Easy Versus Difficult Tasks: Effects on Appraisals and Emotions

Tests in educational contexts often start with easy tasks assuming that this fosters positive experiences—a sense of control, higher valuing of the test, and more positive and less negative emotions. Although intuitive and widespread, this assumption lacks an empirical basis and a theoretical framework. We conducted a field experiment and randomly assigned 208 students to an easy-to-difficult or a difficult-to-easy condition in a mathematics test. Perceived challenge was measured along with control appraisals, value appraisals, and emotions (enjoyment, pride, anxiety, anger, boredom). While students starting with easy tasks felt less challenged than students starting with difficult tasks in Part 1, no differences emerged regarding control and value appraisals and emotions. In Part 2, students who had started with easy tasks proceeded to difficult tasks and reported higher challenge, lower value and control, and less positive and more negative emotions than students who proceeded from difficult to easy tasks. Control and value appraisals mediated these differences between conditions, especially regarding positive emotions. These results cast doubt on the preference for easy-to-difficult over difficult-to-easy task orders, revealing their potential for causing adverse experiences at the end of the test (e.g., reflecting contrast effects).

Residual Effects of Cannabis Use on Effort-Based Decision-Making

Objective:Acute Δ9-tetrahydrocannabinol (THC) administration in humans (Lawn etal., 2016) and rats (Silveira, Adams, Morena, Hill, & Winstanley, 2016) has been associated with decreased effort allocation that may explain amotivation during acute cannabis intoxication. To date, however, whether residual effects of cannabis use on effort-based decision-making are present and observable in humans have not yet been determined. The goal of this study was to test whether prolonged cannabis use has residual effects on effort-based decision-making in 24-hr abstinent cannabis using adults.Method:We evaluated performance on the Effort Expenditure for Reward Task (EEfRT) in 41 adult cannabis users (mean age = 24.63 years, 21 males) and 45 nonusers (mean age = 23.90 years, 19 males). A mixed 2x3x3 ANOVA with age as a covariate was performed to examine the effect of group, probability of winning, and reward amount on EEfRT performance. EEfRT performance was operationalized as % of trials for which the hard (vs. easy) condition was chosen. Pearson’s correlations were conducted to test the relationship between EEfRT performance and measures of cannabis use, anhedonia and motivation.Results:We found that cannabis users selected hard trials significantly more than nonusers regardless of win probability or reward level. Frequency of cannabis use was positively correlated with amount of % hard trials chosen. There were no significant correlations between % hard trials chosen, self-reported anhedonia, or motivation.Conclusions:These results suggest that unlike acute effects, residual effects of cannabis following 24 hrs of abstinence are associated with greater effort allocation during effort-based decision-making.

Interference of Illusory Contour Perception by a Distractor

The visual system is capable of recognizing objects when object information is widely separated in space, as revealed by the Kanizsa-type illusory contours (ICs). Attentional involvement in perception of ICs is an important topic, and the present study examined whether and how the processing of ICs is interfered with by a distractor. Discrimination between thin and short deformations of an illusory circle was investigated in the absence or presence of a central dynamic patch, with difficulty of discrimination varied in three levels (easy, medium, and hard). Reaction time (RT) was significantly shorter in the absence compared to the presence of the distractor in the easy and medium conditions. Correct rate (CR) was significantly higher in the absence compared to the presence of the distractor in the easy condition, and the magnitude of the difference between CRs of distracted and non-distracted responses significantly reduced as task difficulty increased. These results suggested that perception of ICs is more likely to be vulnerable to distraction when more attentional resources remain available. The present finding supports that attention is engaged in perception of ICs and that distraction of IC processing is associated with perceptual load.

Stimulus–response complexity influences task-set inhibition in task switching

Previous studies have found that inhibiting a task set plays an important role in task switching. However, the impact of stimulus–response (S–R) complexity on this inhibition processing has not been explored. In this study, we applied the backward inhibition paradigm (switching between tasks A, B, and C, presented in sets of three) in order to investigate inhibition performance under different S–R complexities caused by corresponding S–R mappings. The results showed that the difficult condition resulted in a greater switch cost than the moderate and easy conditions. Furthermore, we found a significant n−2 repetition cost under the easy S–R complexity that was reversed under the difficult S–R complexity. To verify stability of the reversed n−2 repetition cost in the difficult condition, we recruited another independent sample to conduct an additional experiment with the difficult condition. These results replicated the reversed n−2 repetition cost. These findings suggest that S–R complexity affects task-set inhibition in task switching because the effect of the task-set inhibition was insignificant when the S–R complexity increased; it was only significant under the easy condition. This result was caused by the different cognitive resource assignments.

BEHAVIOUR OF USER OF WOMEN WORKERS OF HERO SUPERMARKET JAKARTA IN FOSTER FAMILY PATTERN

Female workers have to face the reality in supporting family’s financial problem and taking care her children. This is not easy condition, they have to run their role as employee, mothers and wife. To run this decision,Female workers need support from family, parents and environment. The thing that can’t be avoided is, gadget usage as one of tools and gamess in family. The research methods use qualtitave with descriptive data analysis. The result was gained by distributing quesinare in Parenting Seminar which held by Hero Supermarket Workers Assocation in 16 th Mei 2016. The respondents were delegated Female Hero Supermarket workers from east Jakarta.The result showed From 39 responden, 92,3% or the respondent gave smartphone to their children. 35,9% respondent gave smartphone to their children to paly gamess, 20,5% to communicate with their children by whatsapp, message texting and telephone. The relationship and communication between respondents and their husband quite positive. 71,8% showed that they always discuss everything related to family’s matter to their husband, 51,3% don’t have any difficulties to communicate with their husband. Respondents understand that giving smartphone to toddlers will rise negative impact. That’s worry them, but they haven’t figure out the solution to this problem. Female workers in Hero Supermarket has limited access to parenting information. This encourage Hero Supermarket to held the seminar and balance the needs of the worker and make them feel comfort while working and raising their family.

Effectiveness of Diagrammatic Guide Signs at Complex Interchanges

The present work investigated if drivers’ interpretation of diagrammatic arrow signs dropped in accuracy as the number of lanes at an interchange increased. A set of diagrammatic arrow signs were shown to 183 participants as part of a slideshow. Participants were prompted with a navigation objective, briefly shown a picture of a diagrammatic arrow sign that communicated the necessary information for navigation, then they were asked to make a navigation decision. The three factors considered were 1) the total number of lanes on the roadway, 2) the parity of lanes included in each of two branches on the sign, and 3) the difficulty of the navigation task decision. When positioned in an edge lane (easy condition), drivers were good at determining where their lane would lead. When positioned in a center lane (hard condition), their navigation performance improved with an odd number of lanes.

Cognitive Load Reduces Perceived Linguistic Convergence Between Dyads

Speech convergence is the tendency of talkers to become more similar to someone they are listening or talking to, whether that person is a conversational partner or merely a voice heard repeating words. To elucidate the nature of the mechanisms underlying convergence, this study uses different levels of task difficulty on speech convergence within dyads collaborating on a task. Dyad members had to build identical LEGO® constructions without being able to see each other’s construction, and with each member having half of the instructions required to complete the construction. Three levels of task difficulty were created, with five dyads at each level (30 participants total). Task difficulty was also measured using completion time and error rate. Listeners who heard pairs of utterances from each dyad judged convergence to be occurring in the Easy condition and to a lesser extent in the Medium condition, but not in the Hard condition. Amplitude envelope acoustic similarity analyses of the same utterance pairs showed that convergence occurred in dyads with shorter completion times and lower error rates. Together, these results suggest that while speech convergence is a highly variable behavior, it may occur more in contexts of low cognitive load. The relevance of these results for the current automatic and socially-driven models of convergence is discussed.

Brain mechanisms of anxiety's effects on cognitive control in major depressive disorder

BackgroundAdults with major depressive disorder (MDD) demonstrate increased susceptibility to interfering effects of anxiety on cognitive control; although under certain conditions adults with MDD are able to compensate for these effects. The brain mechanisms that may facilitate the ability to compensate for anxiety either via the recruitment of additional cognitive resources or via the regulation of interference from anxiety remain largely unknown. To clarify these mechanisms, we examined the effects of anxiety on brain activity and amygdala–prefrontal functional connectivity in adults diagnosed with MDD.MethodA total of 22 unmedicated adults with MDD and 18 healthy controls (HCs) performed the Tower of London task under conditions designed to induce anxiety, while undergoing a functional magnetic resonance imaging assessment.ResultsDuring the easy condition, the MDD group demonstrated equivalent planning accuracy, longer planning times, elevated amygdala activity and left rostrolateral prefrontal cortex (RLPFC) hyperactivity relative to HCs. Anxiety mediated observed group differences in planning times, as well as differences in amygdala activation, which subsequently mediated observed differences in RLPFC activation. During the easy condition, the MDD group also demonstrated increased negative amygdala–dorsolateral prefrontal cortex (DLPFC) connectivity which correlated with improved planning accuracy. During the hard condition, HCs demonstrated greater DLPFC activation and stronger negative amygdala–DLPFC connectivity, which was unrelated to planning accuracy.ConclusionsOur results suggest that persons with MDD compensate for anxiety-related limbic activation during low-load cognitive tasks by recruiting additional RLPFC activation and through increased inhibitory amygdala–DLPFC communication. Targeting these neural mechanisms directly may improve cognitive functioning in MDD.

Selective Age Effects on Visual Attention and Motor Attention during a Cued Saccade Task

Objective. Visual information is often used to guide purposeful movement. However, older adults have impaired responses to visual information, leading to increased risk for injuries and potential loss of independence. We evaluated distinct visual and motor attention contributions to a cued saccade task to determine the extent to which aging selectively affects these processes.Methods. Nineteen healthy young (18–28 years) and 20 older (60–90 years) participants performed a cued saccade task under two conditions. We challenged motor attention by changing the number of possible saccade targets (1 or 6).Results. Older adults had difficulty in inhibiting unwanted eye movements and had greater eye movement inaccuracy in the hard condition when compared to the younger adults and to the easy condition. Also, an inverse relation existed between performance on the visual and motor components of the task in older adults, unlike younger adults.Conclusions. Older adults demonstrated difficulty in both inhibiting irrelevant saccade targets and selecting correct saccade endpoints during more complex tasks. The shift in relations among attention measures between the younger and older participants may indicate a need to prioritize attentional resources with age. These changes may impact an older adult’s ability to function in complex environments.

A functional MRI study of verbal fluency in adults with bipolar disorder and their unaffected relatives

BackgroundIndividuals with a history of bipolar disorder demonstrate abnormalities of executive function, even during euthymia. The neural architecture underlying this and its relationship with genetic susceptibility for illness remain unclear.MethodWe assessed 18 remitted individuals with bipolar disorder, 19 of their unaffected first degree relatives and 19 healthy controls using functional magnetic resonance imaging (fMRI) and a paced verbal fluency task with two levels of difficulty.ResultsBipolar patients made significantly more errors in the easy level of the verbal fluency task than their relatives or controls. Analysis of variance of fMRI data demonstrated a significant main effect of group in a large cluster including retrosplenial cortex and adjacent precuneate cortex (x=7, y=−56, x=15). All three groups showed deactivation in these areas during task performance relative to a neutral or rest condition. Group differences comprised a lesser amount of deactivation in unaffected relatives compared with controls in the easy condition [F(2, 55)=3.42, p=0.04] and in unaffected relatives compared with bipolar patients in the hard condition [F(2, 55)=4.34, p=0.018]. Comparison with the control group indicated that both bipolar patients and their relatives showed similar deficits of deactivation in retrosplenial cortex and reduced activation of left prefrontal cortex.ConclusionsBipolar disorder may be associated with an inherited abnormality of a neural network incorporating left prefrontal cortex and bilateral retrosplenial cortex.
