Two experiments were conducted to test Bartlett and Dowling's conclusion (1980) that the key of a tone sequence strongly influences recognition for short retention intervals, that the influence decreases with increasing retention time, and that the importance of the melodic interval information increases during the retention interval. Five different retention times were used (1,5,8,15, and 30 sec), together with standard tone sequences with a clear tonal scheme and two different contours (two or four directional contour changes). Subjects with moderate musical experience were able to discriminate tonal imitations and transpositions of the standards at all retention times; the number of contour changes did not influence the responses. It was concluded that interval information can be extracted from sequences with strong cues for a particular key within a very short period of time and that one of the major dimensions of tone sequences is not tonality or nontonality, but rather the degree of tonal clarity. This characteristic even may be superior to the number of contour changes.

Accuracy Relationship

A growing body of research suggests that confidence judgements can provide a useful indicator of memory accuracy under some conditions. One factor known to affect eyewitness accuracy, yet rarely examined in the confidence-accuracy literature, is retention interval. Using calibration analyses, we investigated how retention interval affects the confidence-accuracy relationship for eyewitness recall. In total, 611 adults watched a mock crime video and completed a cued-recall test either immediately, after 1 week, or after 1 month. Long (1 month) delays led to lower memory accuracy, lower confidence judgements, and impaired the confidence-accuracy relationship compared to shorter (immediate and 1 week) delays. Long-delay participants who reported very high levels of confidence tended to be over-confident in the accuracy of their memories compared to other participants. Self-rated memory ability, however, did not predict eyewitness confidence or the confidence-accuracy relationship. We discuss the findings in relation to cue-utilization theory and a retrieval-fluency account.

Invariant Shape

In early cortex, visual information is encoded by retinotopic orientation-selective units. Higher-level representations of abstract properties, such as shape, require encodings that are invariant to changes in size, position, and orientation. Within the domain of open, 2-D contours, we consider how an economical representation that supports viewpoint-invariant shape comparisons can be derived from early encodings. We explore the idea that 2-D contour shapes are encoded as joined segments of constant curvature. We report three experiments in which participants compared sequentially presented 2-D contour shapes comprised of constant curvature (CC) or non-constant curvature (NCC) segments. We show that, when shapes are compared across viewpoint or for a retention interval of 1000 ms, performance is better for CC shapes. Similar recognition performance is observed for both shape types, however, if they are compared at the same viewpoint and the retention interval is reduced to 500 ms. These findings are consistent with a symbolic encoding of 2-D contour shapes into CC parts when the retention intervals over which shapes must be stored exceed the duration of initial, transient, visual representations.

Prior Item

A 4 × 4 factorial design with repeated measures across retention intervals and instructions was employed to determine the effect of instruction on recall ability of movement information from short-term motor memory. Each of the 16 Ss received all 16 possible treatment combinations. While both retention interval and instruction showed significant effects, there was no significant interaction. The reverse-order instruction was affected by the length of the retention interval while the no-prior-item, last-distance, and drop instructions were uninfluenced. No evidence supported the trace-decay hypothesis of forgetting. Ss seem easily able to remove information from memory or ignore information input so it is not represented in memory.

Successive Recall

2 experiments, using paired adjectives, examined the effect of successive recall trials (SRC) that occurred immediately after OL on retention. Retention was measured after 0-, 24-, and 48-hr. retention intervals. The first experiment varied SRC trials (0 vs 10) following OL, and retention interval (0 vs 24 hr.). Exp. II extended the first by increasing the amount of post-OL SRC (0, 10, and 20 trials) and by increasing the retention interval (24 vs 48 hr.). Both experiments measured retention over 10 SRC trials. Correct recall was facilitated by post-OL SRC and increased during SRC trials after 24- and 48-hr. retention intervals. The results suggest that both associative and warm-up processes operate during SRC.

Main Effects

6 24-word English sentences were made up, 2 representing each of 3 levels of meaningfulness. Meaningfulness was defined in terms of the Thorndike-Lorge frequency of the words making up the sentences. The sentences were mounted on memory drums and learned by serial anticipation to a criterion of 100% correct responses or to a lower criterion, equivalent across level of meaningfulness. The retention intervals were 20 min. and 24 hr., the former providing a control for post-criterial drop. The measure of retention was the number of items lost during the interval. The main effects for both retention interval and meaningfulness were significant as was the interaction term between level of learning and retention interval. Because there were no significant interaction terms involving meaningfulness, it was concluded that the main effect for meaningfulness was an artifact resulting from differing degrees of associative strength at the end of learning. This conclusion was reinforced by scrutiny of 24-hr. loss scores, corrected for post-criterial drop.

Following a proaction paradigm, 670 Ss were trained with two lists containing five of the secondary associates (R2) to Russell-Jenkins stimulus words, and were tested 2 min., 20 mm., 2 days, or 28 days later for retention of the second list. During recall, half of the Ss were administered the five stimulus words corresponding to the five R2 words of the second list (stimulated condition), and half did not receive the stimulus words (not-stimulated condition). The stimulus words were divisible into three categories, in effect varying the cultural associative probabilities at each retention interval. Altogether, there were 24 groups completing a 4 × 2 × 3 factorial design. The retention of R2s decreased with time and the effect of stimulation was to raise their level of production above groups not so stimulated. As R2s decreased with time, intrusions of R1s (primaries) and Ra-nS (sum of Ra to R n) became more numerous where the cultural probabilities suggested this ought to happen. After 28 days, Ss still showed strong evidence of the training exposure but performance was more like that of free-associating Ss than that of shorter retention groups. In the not-stimulated condition, intrusions from unidentified sources (classified as Remainder) were more numerous the longer the retention interval. Collectively, these data support the conclusion that the amount of proactive interference via specific pre-experimental word-word habits increases as a function of time. An item analysis suggested a monotonic pattern of rs for forgetting under stimulated conditions, but not under conditions of free recall. This was interpreted to mean that forgetting when stimulated was more a process of complication than simplification and resembles a process sometimes found in motor-skills retention. Other correlational analyses proved useful tools for describing forgetting; questions pertaining to the behavior of items were quite as intriguing as those about Ss. Also, more variance could be accounted for after long than short retention intervals.

Retention Intervals

The length of the interval between the stimulus and response (retention interval) was varied in an automated task involving recall of a threeletter word. The length of the retention interval was not as important a variable as the sequence of presentation of retention intervals of different lengths for 32 mentally retarded residencs of the Austin Stare School. Results suggest that their performance on the automated task might improve if practice is under retention intervals that are longer initially but then decrease during performance.

Previous empirical work suggests that emotion can influence accuracy and cognitive biases underlying recognition memory, depending on the experimental conditions. The current study examines the effects of arousal and valence on delayed recognition memory using the diffusion model, which allows the separation of two decision biases thought to underlie memory: response bias and memory bias. Memory bias has not been given much attention in the literature but can provide insight into the retrieval dynamics of emotion modulated memory. Participants viewed emotional pictorial stimuli; half were given a recognition test 1-day later and the other half 7-days later. Analyses revealed that emotional valence generally evokes liberal responding, whereas high arousal evokes liberal responding only at a short retention interval. The memory bias analyses indicated that participants experienced greater familiarity with high-arousal compared to low-arousal items and this pattern became more pronounced as study-test lag increased; positive items evoke greater familiarity compared to negative and this pattern remained stable across retention interval. The findings provide insight into the separate contributions of valence and arousal to the cognitive mechanisms underlying delayed emotion modulated memory.

Prospective Memory Performance

Objective To examine the effects of interruptions and retention interval on prospective memory for deferred tasks in simulated air traffic control. Background In many safety-critical environments, operators need to remember to perform a deferred task, which requires prospective memory. Laboratory experiments suggest that extended prospective memory retention intervals, and interruptions in those retention intervals, could impair prospective memory performance. Method Participants managed a simulated air traffic control sector. Participants were sometimes instructed to perform a deferred handoff task, requiring them to deviate from a routine procedure. We manipulated whether an interruption occurred during the prospective memory retention interval or not, the length of the retention interval (37–117 s), and the temporal proximity of the interruption to deferred task encoding and execution. We also measured performance on ongoing tasks. Results Increasing retention intervals (37–117 s) decreased the probability of remembering to perform the deferred task. Costs to ongoing conflict detection accuracy and routine handoff speed were observed when a prospective memory intention had to be maintained. Interruptions did not affect individuals’ speed or accuracy on the deferred task. Conclusion Longer retention intervals increase risk of prospective memory error and of ongoing task performance being impaired by cognitive load; however, prospective memory can be robust to effects of interruptions when the task environment provides cuing and offloading. Application To support operators in performing complex and dynamic tasks, prospective memory demands should be reduced, and the retention interval of deferred tasks should be kept as short as possible.
