Organization in visual episodic memory: relationships between verbalized knowledge, strategy use, and performance

Relationships between verbalized knowledge (metamemory), strategy use, and performance were examined in a memory task for visually presented episodes. Kindergarten, second-grade, and fifth-grade students were asked to reconstruct a sequence of pictures forming an episode from an array of original pictures and foils. The episodes varied on two dimensions; materials type and the logic of the sequence. Materials were either typical (familiar animal characters and scenes) or atypical (geometric figures) story materials. Sequences either readily conveyed a story (logical) or were rearranged to present a random ordering of pictures (illogical). Children were questioned about their use of a story line to help remember the picture sequences (general questioning) and were asked more specific questions concerning the reasons for their picture selection during the task (specific questioning). Children at all ages recalled logical sequences better than illogical ones. Second- and fifth-grade children recalled animal episodes better than geometric form episodes. Children at all ages showed a correspondence between strategy use and metamemory as assessed by verbalization of relationships among pictures during the specific questioning. However, when the more typical general question format was used to assess metamemory, strategy use preceded verbalized knowledge of strategy use.     

Developmental differences in empathy with a television protagonist's fear

An experiment was conducted to determine whether children at different ages (3-5 vs 9-11) differ in their tendency to share the emotion of a television character. Subjects were shown a videotape of either a frightening stimulus alone or a character's fear in response to a threatening stimulus that was suggested rather than shown directly. Contrasting predictions were made based on a cognitive-developmental view of the process of empathy vs an automatic conception. Both self-reported emotional reactions and physiological responses were consistent with the cognitive-developmental approach: The younger children were less emotionally aroused by the character's fear than by the fear-provoking stimulus, while the older children responded emotionally to both versions of the videotape. The younger children's lack of empathy was not due to a failure to recognize the nature of the character's emotion. There was some evidence that the older children exhibited a greater tendency to role take than did the younger children.     

The effect of pretraining and feedback on the reasoning of young children

Three experiments are reported in which kindergarten and first-grade children were given one-trial multidimensional reasoning tasks that were modifications of those used by T. C. Toppino (1980, Journal of Experimental Child Psychology, 30, 496–512). In the first two experiments, the nature of the stimulus compounds (partitioned or unitary) was varied in a series of tasks of increasing complexity. First-grade children (Experiment 1) and kindergarten children (Experiment 2) performed extremely well on all of the tasks presented. Experiment 3 was designed to identify factors that contribute to these high levels of performance, relative to those obtained under the conditions used by Toppino (1980). The results indicated that a combination of feedback information and preliminary experience with simple forms of the tasks are sufficient to produce the high performance levels, and that the verbal labeling of stimulus components is not an essential constituent of the training.     

Prototype matching: a strategy for social decision making

College students responded to a series of questionnaires while they were in the process of selecting housing from a choice of seven available options for the coming fall. Questionnaires concerned their self-concepts, their housing prototypes, their preferences in housing, and their goals in housing selection. Overall analyses of the self-to-prototype matching strategy suggest that most students indeed prefer the type of housing for which their prototype of the "representative" resident most closely matches their self-perceptions. More important, we obtained individual differences in attention to self-fit in situations. Of individuals who reported that they had interpersonal goals in the housing selection task, those who reported that many personality characteristics (both positive and negative) were untrue of self were more systematic in their use of the self-to-prototype matching rule, this was also true of low self-monitors. Neither pattern of individual differences obtained for students with practical goals in the housing decision.     

Enhancement of experienced sexual arousal in response to erotic stimuli through misattribution of unrelated residual excitation.

In a pretest, three phases of recovery from a standard physical exercise were determined. In Phase 1, subjects experienced high levels of physiological excitation and recognized that their arousal was due to exercise. In Phase 2, subjects maintained substantial excitatory residues from the exercise but felt that their arousal had returned to base level. In Phase 3, subjects' excitatory responses had decayed, and they knew they had recovered from the exercise. Subjects in the main experiment were exposed to an erotic film in the first, second, or third recovery phase after performing the exercise. Subjects viewing the film during the second recovery phase reported being more sexually aroused by the film and evaluated the film more positively than subjects in the other two conditions. Counter to the notion of arousal as a simple energizer of all behavior, these findings were interpreted as supporting excitation-transfer theory, which posits that residual excitation enhances emotional responses to unrelated, immediately present stimuli only when the prevailing arousal cannot be attributed to its actual source.     

On the duality of simultaneous time and size perception

When subjects are asked to judge the duration and size of visually presented circles that vary in duration and size, perceived duration is directly related to stimulus size and perceived size is, in most cases, directly related to stimulus duration. When subjects are asked to process time and size information simultaneously, their time judgments are the same as when only time processing is required, but their size judgments are less than when only size processing is required. These data are discussed within the context of an explicit model for the processing of size information, added to which is the assumption that time judgments are influenced by the time spent processing size information.     

The effects of dimensional naming upon children’s performance in a modified optional shift problem

In a modified optional shift paradigm, shift and test tasks were administered concurrently to 120 second-grade children. Ss required, during shift learning, to verbalize the values of the previously relevant dimension showed an increase in reversal responding in the test task, whereas those required to verbalize the values of the previously irrelevant dimension showed an increase in nonreversal responding. The results are in good agreement with predictions made from an extension of Hull-Spence discrimination learning theory.
