Inspection times, the change task, and the rapid-response selection task

Three experiments are reported, which are based upon the Wason four-card selection task inspection time paradigm, in which subjects solve computer-presented trials while using a mouse to indicate the card currently under consideration. Evans (1996) had shown that selected cards were inspected for longer than non-selected cards, and this was taken as support for the existence of pre-conscious heuristic processes that direct attention towards relevant aspects of a problem. However, Roberts (1998b) suggested that this inspection time effect is artefactual, due to task format induced biases. Experiment 1 utilized a "change" task: Cards were presented either as selected or not selected, and subjects changed these where necessary. This demonstrated an association between card selection and inspection time independently of one between the act of response and inspection time. Experiment 2 utilized a standard selection task, but subjects either responded within 2 s of each card presentation, or made selections with no time pressure. The curtailment of thinking time increased matching behaviour—more cards matching the terms in the rules were selected—and was replicated in Experiment 3 using a within-subjects design. Overall, the data support Evans' heuristic-analytic framework albeit with some caveats.     

Cultural differences in process and person focus: Congratulations on your hard work versus celebrating your exceptional brain

Cultural differences in process-focused versus person-focused themes were examined using both cultural artifacts (Study 1) and self-reports (Study 2). In Study 1, the contents of Chinese and American graduation and encouragement cards were analyzed for their relative emphasis on person- versus process-focused themes. Person-focused themes center on recipients' stable traits and abilities, and their emotional well-being. In contrast, process-focused themes dwell on the recipients' hard work and effort, and emphasize the importance of continued self-improvement and growth. Messages on Chinese cards were significantly more process than person focused. The reverse was true of American cards. Chinese cards also contained more process-focused (e.g., winding roads) than person-focused images (e.g., student standing on a pedestal). American cards contained more person-focused than process-focused images, although this difference was significant only among encouragement cards. In Study 2, we presented Chinese and American participants with graduation card messages differing in focus. Chinese parents indicated that they would be more likely to select and Chinese students indicated that they would be more likely to receive process- than person-themed graduation card messages. American parents and students showed no effects of message focus. The findings illustrate how cultural beliefs are reflected in cultural artifacts and personal preferences.     

Divided attention interferes with fulfilling activity-based intentions

Two experiments were conducted to examine the effects of divided attention on activity-based prospective memory. After establishing a goal to fulfill an intention upon completion of an ongoing activity, successful completion of the intention generally suffered when attention was being devoted to an additional task (Experiment 1). Forming an implementation intention at encoding ameliorated the negative effects of divided attention (Experiment 2). The results from the present experiments demonstrate that activity-based prospective memory is susceptible to distraction and that implementing encoding strategies that enhance prospective memory performance can reduce this interference. The current work raises interesting questions about the similarities and differences between event- and activity-based prospective memories.     

Retardation in Human Discrimination Learning as a Consequence of Pre-exposure: Latent Inhibition or Negative Priming?

A series of experiments with human subjects, using black-and-white chequerboard patterns, demonstrated that non-reinforced pre-exposure could impair performance in a subsequent learning task. Subjects were invited to take part in a scenario similar to that of a computer simulated card game. Their task was to turn over a series of cards by mouse-clicking on a pack of cards lying face-down, and then to classify these cards intoone of twocategories. In a subsequent task, subjects were asked todiscriminate betweenpairs ofchequerboards, some of which had previously appeared in the initialcategorizationphase: either directly ('fronts') or incidentally ('backs') involved in categorization. In Experiment 1, for those stimuli used as the backs ofthe cards (thatis,those visible ontopof the packof cards), there was asignificant impairment in performance relative to non-pre-exposed control stimuli. Although the impairment appeared to be specific to the stimuli pre-exposed, when the pre-exposed 'backs' were minimally distorted in the discrimination task of Experiment 2, performance was still significantly impaired relative to non-pre-exposed control stimuli. The results of Experiment 2 donot support the interpretation that retardation in learning following masked pre-exposure in human experiments is comparable to latent inhibition following simple preexposure in other animals. Whilst the impairment in performance appears to be similar to that of latent inhibition, the results may, instead, be better understood in terms of the inhibitory processes involved in negative priming. If this is so, then serious doubt is cast on whether latent inhibition has ever been reliably demonstrated in adult humans.     

The contextualization of input and output events in memory

Summary Several observations from everyday life suggest that people are deficient in monitoring their own actions, often forgetting that they have already performed a planned act, or experiencing doubt as to whether they have done so. These observations appear inconsistent with the many laboratory studies that indicate that people are quite efficient in monitoring their own actions. Towards the resolution of this discrepancy we proposed that: (a) output monitoring in real life often requires the retrieval of a specific, contextually framed episode rather than mere familiarity with an event, and (b) output events are less strongly integrated with their environmental contexts than input events are. Therefore, despite the output advantage that is frequently reported in occurrence memory, context memory should be relatively less efficient for output than for input events. This hypothesis received some support in Experiment 1, in which generated verbal responses were remembered better than read responses, but the difference was significantly smaller for context than for occurrence memory. Experiment 2 employed a task simulating a two-person interaction. While occurrence memory was superior for self-performed tasks to that for other-performed tasks, context memory was in fact inferior for the former tasks. These results were seen to suggest that self-initiated actions tend to undergo a weaker contextual integration than events that originate from a source external to the person.     

Tunnel memories for autobiographical events: central details are remembered more frequently from shocking than from happy experiences

In three experiments, undergraduates recorded as many details as possible for autobiographical memories of highly positive and highly negative events in their lives. Experiment 1 replicated earlier findings for memories of highly negative events: Central details were recorded more frequently than peripheral details, and a weak correlation was found between emotional intensity and number of central details. In Experiment 2, undergraduates recorded details of memories of both their happiest and their most shocking events. Central details dominated over peripheral details only in memories of shocking events. This finding was replicated in Experiment 3. Recording memory details affected the participants' moods and generated a mood congruence effect in a subsequent recall of word-cued memories. The finding suggest that tunnel memories--enhanced memory for the central details of an event--are limited to emotionally negative memories. The findings contradict expectations derived from the notion of repression.     

Sensitivity to reinforcer duration in a self-control procedure

In a concurrent-chains procedure, pigeons' responses on left and right keys were followed by reinforcers of different durations at different delays following the choice responses. Three pairs of reinforcer delays were arranged in each session, and reinforcer durations were varied over conditions. In Experiment 1 reinforcer delays were unequal, and in Experiment 2 reinforcer delays were equal. In Experiment 1 preference reversal was demonstrated in that an immediate short reinforcer was chosen more frequently than a longer reinforcer delayed 6 s from the choice, whereas the longer reinforcer was chosen more frequently when delays to both reinforcers were lengthened. In both experiments, choice responding was more sensitive to variations in reinforcer duration at overall longer reinforcer delays than at overall shorter reinforcer delays, independently of whether fixed-interval or variable-interval schedules were arranged in the choice phase. We concluded that preference reversal results from a change in sensitivity of choice responding to ratios of reinforcer duration as the delays to both reinforcers are lengthened.     

Doing unto future selves as you would do unto others: psychological distance and decision making

Four experiments showed that the decisions people make for future selves and other people are similar to each other and different from their decisions for present selves. Experiments involved decisions to drink a disgusting liquid for scientific purposes (Experiment 1), tutor peers during exam week (Experiment 2), receive e-mails for charity (Experiment 3), and defer a lottery prize for a larger one (Experiment 4). These findings seemed to be at least partially rooted in the tendency for decisions regarding the ongoing, present self to be uniquely influenced by internal subjective experience. Specifically, these effects emerged for real, but not hypothetical, decisions. Also, they were mitigated by manipulations that altered participants' attention to present or future subjective experience. In addition, when participants' subjective experience primarily involved empathy for others (Experiment 3), their decisions on behalf of present selves were more generous than their decisions for future selves and others. Applications are discussed.     

Social transmission of disinhibition in young children

The present study examined whether young children's behaviors in the Dimensional Change Card Sorting task can be influenced by their observation of another person performing the task. Experiment 1 showed that after children watched an adult sorting cards according to one rule, although the children were instructed to sort the cards according to a new rule, most 3-year-olds made perseverative errors and used the observed, old rule to sort the cards instead of the new rule. However, only some 4-year-olds and few 5-year-olds made the same mistake. Experiments 2, 3 and 4 showed that the younger children took into consideration social pragmatic information displayed by the adult model when deciding to use the old rule or the new rule. When the model appeared to know that she sorted the cards incorrectly (Experiments 2 and 3), or was uncertain whether she sorted cards correctly (Experiment 4), most 3-year-olds no longer committed perseverative errors. When the adult model was confident about her sorting or oblivious to her sorting errors, most 3-year-olds made perseverative errors. These results taken together suggest that social observation can lead to disinhibitions. In other words, disinhibition can be transmitted socially from one person to another.     

What happens if you retest autobiographical memory 10 years on?

Burt (1992a, 1992b) reported data on the autobiographical memory of diarists for events that had occurred on average 3.3 years earlier. This paper reports data on 11 of the diarists, who were recontacted after a further 10 years and who agreed to a retest of their memory. Estimates of event date and event duration from the two recall attempts were compared. As predicted, duration estimation was extremely stable and showed no detrimental effects of the additional 10 years of retention interval. Estimation of event date was predicted to show an increase in forward telescoping due to the increased remoteness of the event sample, but, contrary to this prediction, backward telescoping dominated dating errors. A combination of the establishment of a recent boundary and Kemp's (1999) associative model of dating is proposed as an explanation for these results. It is argued that the nature of dating errors may depend on the time of the event's occurrence in the life span and the age of the individual dating the events.     

The development of children's regret and relief

Previous research found that children first experience regret at 5 years and relief at 7. In two experiments, we explored three possibilities for this lag: (1) relief genuinely develops later than regret; (2) tests of relief have previously been artefactually difficult; or (3) evidence for regret resulted from false positives. In Experiment 1 (N=162 4- to 7-year-olds) children chose one of two cards that led to winning or losing tokens. Children rated their happiness then saw a better (regret) or worse (relief) alternative. Children re-rated their happiness. Regret after winning was first experienced at 4, regret after losing and relief after winning were experienced at 5 years and relief after losing at 7 years. Experiment 2 (N=297 5- to 8-year-olds) used a similar task but manipulated children's responsibility for the outcome. Greater responsibility for the outcome resulted in a greater likelihood of an experience of regret and relief. Results support that previous tests of relief were artefactually difficult and regret and relief are experienced earlier than previously thought.     

现实预期和意愿预期在文本阅读中的激活强度

文本阅读中,读者往往对事件的后续发展进行预期推理。预期推理有两种倾向,要么是倾向于根据客观现实条件进行的现实预期,要么是倾向于根据主观个人意愿进行的意愿预期。两个实验探讨了文本阅读中读者产生的现实预期和意愿预期的激活强度。结果发现,现实预期和意愿预期都可以在阅读中即时产生,意愿预期强于现实预期;把读者分为"情感导向型"和"非情感导向型",发现"情感导向型"的读者,阅读过程中产生的意愿预期强于现实预期,而"非情感导向型"的读者则不是。     

The effect of cue Relevance,Ambiguity, and self-reported hostility on tat responses

The interaction of cue relevance and ambiguity was studied. Ss high or low in self-reported hostility were administered 8 T A T cards, half of which were high in hostility cue relevance, half low. Half of each subset, in turn, was high in ambiguity, half low. Highly relevant cards tended to elicit more aggressive content than low relevant cards, and stories to ambiguous cards tended to contain more aggressive themes than unambiguous ones, independent of hostility relevance. Hostile Ss tended to be best discriminated from non-hostile Ss on highly relevant cards, where they responded with more aggressive themes. Results were contrasted with previous findings and it was concluded that consistent with findings where hostility is defined by observation or arousal, highly relevant cues are most sensitive to hostility level. While greater expression of negative content, increments in ambiguity did not add to the sensitivity of the stimuli.     

"Remember where you last saw that card": children's production of external symbols as a memory aid

Four experiments examined the age at which children start to use external symbols to aid their memory and how external symbol use affects both their memory performance and information allocation strategies. In Experiment 1, children in Grades 1, 3, 5, and 7 played a memory card game (Concentration) twice, once with the opportunity to make notes to aid performance and once without the opportunity. Grades I and 3 students tended to produce nonmnemonic notations, whereas Grades 5 and 7 students were more likely to produce functional, adultlike notations that aided performance in the task. In Experiments 2a and 2b, unexpected removal of children's notations led to a decrease in performance. suggesting that the spontaneously produced notations were being used as an external store rather than as an aid to encoding information. Experiment 3 examined whether all information was placed in external storage or if some types of information remained in memory. Grade 7 students who had their notations unexpectedly taken away were able to recognize the identity of the cards they had previously seen but had more difficulty remembering their locations. They appeared to place the location information mainly in external storage while retaining the identity information in memory. These results suggest that in mid-childhood, children begin to distribute information actively between internal and external memory storage.     

Student Changes, Program Influences, and Adult Development in One Program of Counselor Training: An Exploratory Inductive Inquiry

This qualitative study explored how students in 1 program changed as a result of their professional preparation experience. We interviewed 15 counseling students via one-to-one interviews and a focus group. Students were asked how they had changed and what had influenced those changes in their educational experience. Responses were clustered with the assistance of a text analysis computer program. Three broad change themes were named (1) increased reflexivity, (2) increased autonomy, and (3) capacity for dialogue. Four program influences were also identified. They are providing students with (1) experiences in social construction of knowledge, (2) experiential learning, (3) opportunities for independent thinking, and (4) a supportive environment. Connections to adult-development themes and specific instructional strategies that are suggested by the data are named.

Greater responsibility for the outcome resulted in a greater likelihood of an experience of regret and relief. Results support that previous tests of relief were artefactually difficult and regret and relief are experienced earlier than previously thought.     

Ordering autobiographical experiences

This study examined individuals' memory for the temporal order of autobiographical events and for the components that constitute autobiographical events. Study 1 measured performance on an across-event ordering task that involved the chronological arrangement of cards that displayed event labels. Results indicated poor ordering ability across events, but a reasonable ability to order clusters of events. Study 2 compared within-event and across-event ordering using computer-presented digital photographs. Participants were better at ordering the photographs in their own across-event trials than in their within-event trials. The results are discussed in terms of the retrieval of temporal information under within- and across-event conditions.     

Infants' formation and use of categories to segregate objects

Four- and-a-half-month-old infants' (N = 100) category formation and use was studied in a series of five experiments. For each experiment, the test events featured a display composed of a cylinder and a box. Previous research showed that this display is not clearly parsed as a single unit or as two separate units by infants of this age. Immediately prior to testing, infants were shown a set of category exemplars. Knowledge about this category could help infants disambiguate the test display, which contained a novel exemplar of this category. Clear interpretation of the test display as composed of two separate units (as indicated by infants' longer looking at the move-together than at the move-apart test event) was taken as evidence of category formation and use. In Experiments 1 and 5, infants' prior experience with a set of three different boxes that were similar to the test box facilitated their segregation of the test display. Experiment 2 showed that three different exemplars are necessary: prior experience with any two of the three boxes used in Experiment 1 did not facilitate infants' segregation of the test display. Experiment 3 showed that variability in the exemplar set is necessary: prior experience with three identical boxes did not facilitate infants' segregation of the test display. Experiment 4 showed that under these conditions of very brief prior exposure, similarity between the exemplar set and test box is necessary: prior experience with three different boxes that were not very similar to the test box did not facilitate infants' segregation of the test display. Together, these findings suggest that: (a) number of exemplars, variability, and similarity in the exemplar set are important for infants' category formation, and (b) infants use their category knowledge to determine the boundaries of the objects in a display.     

Developmental relationships among metamemory,elaborative strategy use,and associative memory

Two experiments examined the relationships among metamemory knowledge, the use of associative memory strategies like elaboration, and cued-recall memory. In Experiment 1, 5th and 12th graders verbalized their strategies while studying noun pairs; their cued-recall memory of those pairs was then tested. Metamemory knowledge was assessed before or after this task. ANOVAs revealed developmental increases in associative strategies, cued recall, and metamemory. Multiple regression indicated the increase in associative strategies predicted all but 4% of the increase in cued recall; metamemory development in turn predicted all but 4% of the increase in associative strategies. Metamemory was a better predictor than a nonverbal measure of intelligence. The strong relationships were due partly to methodological refinements, including a counterbalanced design, a direct strategy measure, a reliable composite rather than single-item metamemory measure, ordinal rather than dichotomous scoring of metamemory items, and regression rather than χ² analyses. The results of Experiment 1 were replicated in Experiment 2. Metamemory development also predicted most of the grade difference in cued recall that remained after study strategies were equated by elaboration instructions, suggesting it may explain improvements in retrieval strategies as well.
