Three theories of self-disclosure exchange

The present study tested predictions derived from equitable exchange, social attraction, and normative information theories of self-disclosure. Variables relevant to each theory were manipulated orthogonally in the following factorial design: (1) intimate vs. superficial vs. no confederate disclosure, (2) positive vs. negative evaluation delivered by the confederate, and (3) intimate vs. non-intimate disclosure as normative for the experimental situation. Groups in which the subject was exposed to one of the independent variables in the absence of the others were included, to yield 18 cells with 10 female subjects per cell. The findings conformed to equitable exchange theory, in that subjects were more willing to disclose to a high- than a low-revealing partner. However, disclosure appeared to be suppressed in response to low disclosure, rather than enhanced by intimate disclosure. Also, true reciprocity of disclosure did not occur, in that subjects did not completely match the intimacy of the confederate. Normative information proved to be a potent determinant of disclosure tendency. No support was found for social attraction theory. Although confederate evaluation was the best predictor of interpersonal attraction, it was the poorest predictor of intent to disclose. Attraction was not found to parallel disclosure level.     

Updating memory using mnemonic devices

The process of memory updating enables people to recall information most recently associated with a particular stimulus context and to ignore or forget information previously associated with it. In a series of five experiments utilizing mnemonic devices it was found that when associative interference was maximized, only a limited disruption of updating resulted. In addition, mnemonic recall was not dependent on the utilization of higher-order memory components. However, support was found for the hypothesis that memory can be searched using temporal cues and for the idea that the size of the search set formed in memory is important. It was found that the older the event was to be recalled, the greater were the number of events in the search set and therefore the greater was the magnitude of the recall error. The size of the search set created in memory and the role of temporal-contextual cues in defining this search set may be important factors not only in mnemonic recall but in other types of learning and recall as well.     

Binocular disparity as a discriminable stimulus parameter for young infants

The ability of 8-week-old infants to discriminate between projected stereograms with and without retinal disparity was tested with an habituation-dishabituation paradigm. Infants in two experimental groups received six trials with either the disparity or the nondisparity stimulus and then were given two trials with the other display. Infants in two control groups viewed the same stimulus, either disparity or nondisparity, on all eight trials. There was a suggestion of some response decrement over time in both cardiac deceleration and sucking suppression, although this effect was not significant. However, significant increment was obtained on the dishabituation trials for heart rate in the group that was shifted from the nondisparity to the disparity stimulus. These results were interpreted as indicating that the infants could discriminate between stimuli when the only difference between them was binocular disparity.     

A biographical data analysis of career patterns in engineering

This study focuses on an instrument that appears useful for career guidance or job assignment purposes — the Biographical Data Blank. Responses of three groups of engineers (holding research and development, management, and nonengineering positions) to a life history questionnaire were analyzed. Results indicate that groups could indeed be differentiated using response patterns. In addition, items defining these patterns were related to demands of actual career paths chosen.     

Information-gathering strategies in hypothesis-testing

Three experiments were conducted to investigate the informational factors affecting the kinds of questions people ask for testing a hypothesis about another's personality. In Experiment 1, subjects formulated by themselves questions to test either the hypothesis that the interviewee is polite or the hypothesis that he is impolite. The boundary of the hypothesis was set either at an extreme or at an intermediate point on the trait dimension. Experiment 2 also varied the location of the boundary, but the hypotheses concerned extroversion-introversion and subjects chose questions from a predetermined list of questions that asked either about extroverted features or introverted features and that were either low or high in diagnostic value. Both studies found that subjects preferred to ask about features that are consistent with the hypothesis only when the boundary was extreme. In contrast, diagnostic features were preferred in all conditions. Experiment 3 showed that subjects' judgment of the diagnosticity of the various kinds of questions for discriminating at different boundaries paralleled subjects' preferences among these questions. These results were interpreted as providing support for the diagnostic strategy in social information gathering.     

Cross-response mode consistency in risk taking as a function of self-reported strategy and self-perceived consistency

Earlier work (Slovic, Journal of Personality and Social Psychology, 1972, 22, 128–134) has found that consistency in preference for the same stimuli across two response modes, selling price and choice, is only moderate. The present study followed the same procedure and also asked subjects to report the strategies they used to determine their preferences and to state how consistent they usually were in gambling tasks. Greater consistency was found for those (1) who reported strategies for both response modes, (2) whose strategy type matched across response modes, and (3) who perceived themselves as consistent. Strategy differences were also found across response modes. The results were discussed in terms of the usefulness of assessing subjective task interpretation in predicting consistency and for the general desirability of greater idiographic assessment for increased predictability.     

Area-matching strategies used by young children

Across three studies, conditions were varied under which children aged 4–5 years matched the area of a rectangle with a given width (or height) to that of a square. In the first study, subjects observed the rectangle being changed in height from trial to trial and had access to their immediately preceding response. Under these conditions, rectangle width (the dimension under subject control) was a linear decreasing function of rectangle height. This function was interpreted as evidence for a hypothetical addition/subtraction strategy for maintaining equality in area between the comparison rectangle and the standard square. As a test of this hypothesis, in a second experiment the subjects were denied access to their immediately previous response, and in a third study they were also unable to observe the rectangle as it was altered by the experimenter between trials. The purpose of these changes was to remove the information necessary for readily implementing an addition/subtraction strategy. In both studies, area matches seemed to be based on a side-matching strategy, such that subjects matched one dimension of the rectangle to one side of the standard square. It was suggested that young children use different cues or strategies with different variants of the matching task because they do not possess a fixed, specific concept of area.     

Preference for shock signals as a function of the temporal accuracy of the signals

Three groups of rats were exposed to pairs of three different contingencies on two sides of a shuttlebox. One signaled contingency provided 10-min danger and safety cues plus an additional 10-sec cue immediately preceeding shock (P-S), another signaled contingency provided 10-min danger and safety cues but random 10-sec cues with respect to shock (R-S), and an unsignaled contingency provided no safety period, but only a 20-min danger period during which shock could occur (NS). Signaled P-S and R-S contingencies were preferred in a choice test to the unsignaled NS contingency, and P-S was preferred to R-S. Independent tests of the fear-eliciting properties of the cues made in an off-baseline test of suppression of ongoing exploration indicated more freezing (fear) to the 10-sec cue in rats experiencing the P-S contingency. The results were interpreted as indicating a preference for cues providing more precise information about the temporal location of shock even when those cues were fear-eliciting.     

Coding strategies and cerebral laterality effects

In a short-term recognition memory task, Ss were given relational imagery and rehearsal coding strategies in different sessions, with probes presented to the left or right cerebral hemisphere. Consistent with a model of separate processing systems for verbally and visually coded information, Ss yielded significantly faster response latencies for probes to the left hemisphere than the right when employing the rehearsal strategy, and significantly faster latencies for probes to the right hemisphere than the left when using the imagery code. This suggests that cerebral laterality effects are functionally related to coding strategies, and argues for the inclusion of imagery, or generated visual information, as part of the visual processing system. As such, generated visual information may be viewed as a coding alternative to verbal mediation.     

Eye movements of children, adults, and elderly persons during inspection of dot patterns

The effectiveness of three fading and two nonfading procedures were compared in training kindergarten children on an oddity problem in which shape was the relevant dimension. The fading procedures employed supplementary cues which were gradually eliminated during training. The cues included either saturating the odd stimulus with a red color, saturating the nonodd stimuli with a red color, or varying the degree of illumination of the nonodd stimuli. One nonfading group received training on a structurally simpler oddity problem prior to transfer to a more complex oddity problem, and a second nonfading group received the standard oddity training procedure. While significant differences in acquisition were not obtained between training groups, the oddity task performance and the results from a test of dimensional observation revealed that the fading procedures were differentially effective in transferring Ss′ observation from the dimension of the fading cue to that relevant for solution of the oddity problem.     

The relative contributions of predictiveness and salience in flavor aversion learning

Two experiments investigated the relative influence of cue predictiveness and stimulus salience on flavor aversion learning. In the first study experimental subjects experienced a nonsalient strawberry flavor and a different, more salient flavor prior to illness on each of the first three conditioning trials; the nonsalient strawberry and salient lemon were paired with illness on the fourth trial. This treatment resulted in a strong aversion to the strawberry flavor and on aversion to the lemon flavor. In contrast, animals which had experienced only a single pairing of strawberry, lemon, and illness acquired a strong aversion to lemon and no aversion to strawberry, while animals which had experienced only the pairing of different flavors and illness on each of the first three trials developed a strong aversion to both strawberry and lemon. Experiment 2 replicated the results of the experimental condition of the first study but also included a “blocking” condition in which subjects received three strawberry and illness pairings prior to a strawberry-lemon-illness pairing. Subjects in the blocking condition developed only a weak aversion to strawberry, and this aversion did not block the development of a strong lemon aversion. Apparently, in order for a nonsalient flavor cue to block the acquisition of an aversion to a more salient cue, the nonsalient flavor must not only be paired with illness but also be more predictive of illness than the more salient flavors also paired with illness. The data were discussed in terms of the R. A. Rescorla and A. R. Wagner's associative model (1972, in Classical conditioning II: Current research and theory, New York: Appleton-Century-Crofts), R. A. Rescorla's catalytic model (1982, Journal of Experimental Psychology: Animal Behavior Processes,8, 131–141), and N. J. Mackintosh's attentional model (1975, Psychological Review,82, 276–298) of conditioning.     

Some effects of task relevance and friendship on helping: You don't always help the one you like

It was hypothesized that being outperformed on a task that is relevant to one's self-definition is threatening to self-esteem, and that this threat is greater when one is outperformed by a friend rather than by a stranger. When another's performance threatens self-esteem, persons will be less likely to help the other by making the task easy. To test these hypotheses, 52 friendship pairs participated with strangers in a word identification task described either as a measure of important skills (high relevance) or as a game (low relevance). Participants chose clues for both a friend and a stranger to use in identifying target words. As predicted, they gave harder clues under high-relevance than under low-relevance conditions. Moreover, they gave harder clues to strangers than to friends under low-relevance conditions, but gave harder clues to friends than to strangers under high-relevance conditions.
