Self-versus drug-produced relaxation and the effects of instructional set in standardized systematic desensitization

Snake fearful college students underwent Standardized Systematic Desensitization (SSD) treatment in which they received instructions designed to induce cognitions of either self- or drug-produced relaxation. Half of the subjects in each of these conditions were also given high expectancy therapy instructions and low expectancy therapy instructions respectively. All four SSD groups showed significantly greater improvement than a no-treatment control group on both the behavior avoidance test (BAT) and the self-report measure of fear. No differences between self- and drug-attributions of relaxation were found on any measure. Subjects' high expectancy ratings were significantly correlated with improvement on self-report measures but not related to BAT performance.     

Effects of sucrose concentration and goal units on runway behavior in the rat

Experiment 1 investigated the between-S and within-S effects of sucrose concentration (32 and 6%) and number of goal units (equal volumes of sucrose presented in single or multiple goal cups). The goal-unit variable had no effect on behavior under any of several test conditions employed. Within-S effects of sucrose concentration were approximately equal to between-S effects; no contrast effects were found. When 64 and 6% sucrose solutions were used as reinforcers in Experiment 2, a simultaneous, but not a successive, negative contrast effect was found. Results were discussed in terms of possible functional differences between the successive and simultaneous contrast paradigms and between sucrose solutions and solid food as reinforcers.     

Interactive effects of deprivation in the albino rat

The interactive effects of feeding and drinking schedules were investigated in three experiments. Twenty-four hour water-deprived rats consumed their entire obligatory water intake prior to feeding, whereas 24-hr food-deprived rats consumed only small quantities of food prior to drinking. This drinking was apparently due to a shift of water stores rather than an actual negative water balance. Experiment 3 investigated the effects of 24, 48, or 72 hr of water, food, or total deprivation. Water-deprived rats did not adequately suppress food intake and became thirstier than totally deprived rats. The effects of total deprivation were essentially identical to those of food deprivation. These experiments indicate the degree to which deprivation schedules impose restrictions on the reinforcement parameters of behavioral experiments.     

Interference in memory for pictorial information

Subjects studied either faces composed from visual features or verbal facts composed from concepts. Recognition times were increased for both faces and facts when they were composed of elements that occurred in multiple study items. In Experiment 1 the interfering effect of other study items was much larger for verbal facts than for faces. This difference was largely eliminated in Experiment 2 where care was taken to control the features by which the faces were encoded. Experiment 2 also showed that verbal information could interfere with pictorial information and vice versa. However, this cross-modality interference was much weaker than within-modality interference. The data are consistent with the ACT theory in which pictorial material and verbal material are stored together in an abstract propositional network. The subnode model (Anderson, Language, memory, and thought, Hillsdale, N. J.: Lawrence Erlbaum, 1976) can account for the greater within- than cross-modality interference.     

Individual differences and memory for faces,pictures, and words

People who had performed exceptionally well or badly on facial recognition tests between 1 and 4 years previously were given three recognition tasks, one involving faces, one involving paintings, and a third using visually presented words. Those selected as good recognizers were better on the recognition of faces and paintings, but they did not differ in verbal memory. This result suggests that people who are particularly good at facial recognition have a generally good visual memory that is separate from verbal memory.     

Trait anxiety,stress, and learning a test of Saltz's hypothesis

Behavioral predictions from Saltz's, Spence's, and Spielberger's interpretations of trait anxiety were tested in a complex verbal learning task. Fifty-three high-anxious and 52 low-anxious male college students were randomly distributed to test conditions of failure-stress, pain-stress, or neutral instructions. The learning data revealed that high-anxious-failure and low-anxious-pain Ss were disrupted and supported Saltz's hypothesis; self-reported anxiety (A-State scale, STAI) was observed only in high-anxious-failure Ss and supported Spielberger's theory of the arousal of state anxiety as a function of trait anxiety. However, the contradiction between self-reported anxiety and learning behavior in low-anxious-pain Ss indicated that the verbal report of these Ss was an inaccurate or insensitive index of arousal.     

Advertising's misinformation effect

This research explores whether post-experience advertising alters information learned in a consumer's direct experience. An advertising misinformation effect was obtained for colour memory of a previously seen candy bar wrapper upon both visual and verbal misinformation. However, the misleading visual information produced more ‘remember’ judgements than misleading verbal information. This advertising misinformation effect did not dissipate when the source was discredited. We found that such memory changes can be directly linked to consumer subjective judgements and choices when the misleading information is particularly salient. Not only do these findings constitute a novel generalizability of the misinformation effect, they also have implications for social policy research on deceptive advertising.

Majority influence,minority influence and conversion behavior: A replication

A recent experiment by Moscovici and Personnaz (Journal of Experimental Social Psychology 1980, 16, 270–282) showed that whereas a majority produces merely compliance, or a change in the individual's verbal responses, a minority induces conversion, or a true change in one's subjective judgments. Because of the theoretical significance of these findings and because of their inconsistency with data from other experiments, an exact replication and extension of this experiment was performed. There was no evidence of compliance in any social influence condition. Instead, and in contrast to Moscovici and Personnaz, both a majority and a minority produced “conversion” behavior. Subjects' behavior is interpreted as the expression of an improved perception, resulting from a heightened level of attention to the object of judgment under social influence conditions.     

The effects of a memory aid on three types of conservation judgments

Twelve boys and 12 girls at each of 3 ages (4, 5, and 6 years) were tested on three types of conservation judgments (qualitative, quantitative, and equivalence) on both continuous and discontinuous substances. Half of the subjects were provided a memory aid while the other half were not. Conservation ability was determined both with and without verbal justification. The memory aid increased the number of equivalence conservation responses only when verbal justification was not required. The number of subjects conserving on each of the three tasks varied as a function of the scoring criteria used. Type of materials, sex, and age effects were found. The role of transitive inferences and memory in the equivalence conservation task was discussed. Inconsistencies in previous research due to different scoring techniques were noted.     

Observational goals and schema activation: A theoretical framework for behavior perception

A framework for behavioral observation is described in which the processing of a stream of behavior is influenced by an individual's prior knowledge about behavior, organized into cognitive “schemas.” It is proposed that observational goals determine the selection of goal-relevant schemas which, in turn, influence the observer's processing of an actor's behavior. Subjects watched a series of videotaped sequences featuring a female actor with instructions either to form an impression of her or to remember the details of the tasks she engaged in. They were then asked to answer questions that were either consistent or inconsistent with these instructions. Subjects were also instructed to unitize the actions or events that occurred in the sequence (D. A. Newtson, Journal of Personality and Social Psychology, 1973, 28 28–38). According to the unitizing measure, subjects observing with different goals attended to different behavioral features. Further, impression-forming subjects were apparently more influenced by their implicit theories of personality than were task-learning subjects when asked to give ratings of the actor's personality, and task-learning subjects were relatively more accurate in recalling task-related details. Implications of this framework and these results for research in behavioral unitization and implicit personality theory are discussed.     

The effect of modification of expressive displays on vicarious emotional arousal

Several recent experiments have demonstrated that modulation of the facial expressive response is accompanied by changes in autonomic arousal and subjective response to painful stimuli. The present study asked whether facial self-regulation may also bring about changes in covert vicarious emotional experience. Three groups of subjects were exposed to a videotaped model displaying intermittent pain to shock in a differential vicarious autonomic conditioning paradigm. Subjects in the inhibit and amplify groups were asked, respectively, (a) to inhibit their facial muscles or (b) to pose a facial response of pain when the model was shocked. It was predicted that the inhibit group would show less autonomic arousal to the model's expressive display (empathy) and less conditioning (as measured by skin conductance and heart rate change), and the amplify group more empathy and conditioning, than a third group who was given no facial instruction. In fact, the amplify group showed more skin conductance arousal, heart rate acceleration, and activity in response to the model's expressive display of pain than did the other two groups (which were not different from each other), but no more autonomic or facial conditioning. The overall pattern of physiological data is interpreted as generally supportive of a facial feedback theory of emotion: where significant between-groups' differences were obtained in facial activity, as in vicarious instigation, autonomic arousal differences also emerged; where no expressive differences were obtained, as in vicarious conditioning, no differences in autonomic arousal were found.     

Learning style,judgements of learning,and learning of verbal and visual information

The concept of learning style is immensely popular despite the lack of evidence showing that learning style influences performance. This study tested the hypothesis that the popularity of learning style is maintained because it is associated with subjective aspects of learning, such as judgements of learning (JOLs). Preference for verbal and visual information was assessed using the revised Verbalizer‐Visualizer Questionnaire (VVQ). Then, participants studied a list of word pairs and a list of picture pairs, making JOLs (immediate, delayed, and global) while studying each list. Learning was tested by cued recall. The results showed that higher VVQ verbalizer scores were associated with higher immediate JOLs for words, and higher VVQ visualizer scores were associated with higher immediate JOLs for pictures. There was no association between VVQ scores and recall or JOL accuracy. As predicted, learning style was associated with subjective aspects of learning but not objective aspects of learning.     

Proportionality,linearity, and parameter constancy: Messick and Sentis reconsidered

Messick and Sentis found greater support for weak proportionality in subjects' outcome allocations (suggesting that subjects wish to maintain a constant ratio between outcomes across situations when inputs are held constant) than for constant differences between outcomes. They claimed that their data thus provided stronger support for Adams' ratio definition of equity than for Harris' linear formula. A dialogue between the two sets of authors establishes that (1) so far as their specification of fair outcomes is concerned, Adams' formula is a special case of the linear formula; (2) weak proportionality does not necessarily follow from Adams' formula and can be derived from the linear formula; (3) Adams' formula applied to subjective (rather than experimenter-defined) inputs nevertheless provides a more natural base from which to derive weak proportionality than does the linear formula in its general form; (4) excellent fits to several sets of data, including much better fit to Messick and Sentis' data than that provided by weak proportionality, are obtained if we assume that subjects use allocations which are a weighted average of those implied by Adams' formula, the Equality principle, and Komorita and Kravitz' Equal Excess Norm; and (5) a fit to Messick and Sentis' data that is almost as good as that provided by the weighted solutions model is obtained by assuming that subjects apply Adams' formula to subjective inputs and subjective outcomes that are different from the corresponding experimenter-defined values. It is agreed that the delineation of the relationships among observable properties of outcome distributions, alternative equity formulae, and different psychological processes is as important as it can be devious.     

A new look at selective exposure

The relevance of the personality dimension “repression-sensitization” (D. Byrne in B. A. Maher (Ed.), Progress in experimental personality research, Vol. 1, NY: Academic Press, 1964, pp. 169–219) to selective exposure processes was investigated. Experimental repressors (who typically employ “avoidance” strategies in dealing with threatening stimuli) and experimental sensitizers (who generally “approach” threatening stimuli) were allowed to choose and keep one of two pairs of painting reproductions, each pair containing one positively and one negatively valued painting. After the decision, which experimental subjects believed terminated the experiment, subjects were allowed to inspect the alternatives ad libitum for 75 sec. Eye gaze during this period was unobtrusively videotaped. Compared to their matched controls, who were simply asked to inspect the paintings in order to decide which ones they liked best, experimental repressors inspected paintings that were consonant with their choices and avoided looking at paintings that were dissonant with their decisions. Experimental sensitizers did not manifest such postdecisional selective exposure. The implications of these results for past and future research on dissonance-produced selective exposure were discussed.     

Similarities and differences in visual and spatial perspective-taking processes

Processes for perspective-taking can be differentiated on whether or not they require us to mentally rotate ourselves into the position of the other person (Michelon & Zacks, 2006). Until now, only two perspective-taking tasks have been differentiated in this way, showing that judging whether something is to someone’s left or right does require mental rotation, but judging if someone can see something or not does not. These tasks differ firstly on whether the content of the perspective is visual or spatial and secondly on whether the type of the judgement is early-developing (level-1 type) or later-developing (level-2 type). Across two experiments, we tested which of these factors was likely to be most important by using four different perspective-taking tasks which crossed orthogonally the content of judgement (visual vs. spatial) and the type of judgement (level-1 type vs. level-2 type). We found that the level-2 type judgements, of how something looks to someone else and whether it is to their left or right, required egocentric mental rotation. On the other hand, level-1 type judgements, of whether something was in front of or behind someone and of whether someone could see something or not, did not involve mental rotation. We suggest from this that the initial processing strategies employed for perspective-taking are largely independent of whether judgements are visual or spatial in nature. Furthermore, early developing abilities have features that make mental rotation unnecessary.     

Comparatives,logical structures,and encoding in a transitive inference task

Four- to five-year-old children were asked questions on length involving single or double comparatives in a transitive inference task. The number of comparatives varied within or across pairs. The pairs of sticks were colorcoded. Initial pair-wise discrimination training on four adjacent pairs from a five-stick array with only verbal feedback was followed by tests, without feedback, on all possible pairs. When both comparatives were used, Ss learned adjacent pairs faster and more often reached criterion than when only one comparative term was used in training. In testing, Ss were successful on transitive inference tests only when the double-comparative relation was used within pairs during training. Retraining with visual feedback increased the number of Ss solving the inference test only in this condition. The findings are discussed in terms of how children may use processes other than logical operations to make transitive inferences.     

Learned helplessness and IQ differences

Two groups of adult Ss differing in verbal IQ were compared in a learned helplessness experiment involving cognitive tasks and non-contingent rewards. The mean IQs for the two groups were 131 and 117. As predicted, the higher IQ Ss performed better overall and showed greater awareness of the response-outcome contingency. Their test-task performance was also more affected by the contingency manipulation although this occured only with success feedback. Implications of the results for cognitive accounts of human helplessness are discussed.     

The child's memory for actional, locational, and serial scenes

Three-, four-, and six-year-old children (N = 180) were tested for recall of a toy missing from a previously seen display of four toys. Toys were displayed initially as a series (StoS), as a unit (UtoU), or moved from a series to a unit as S watched (StoU). There was a significant increase in memory for the missing toy with age. In addition, children viewing StoU displays remembered significantly more toys than did children viewing the other displays, independent of age. Twenty-five percent of the 6-year-olds rehearsed spontaneously while viewing the displays. Results indicated that the nature of a memory unit does not change with age, that memory improves with age, and that separate visual and verbal memories are operative in Ss in this age range.     

Beauty in the blink of an eye: The time course of aesthetic experiences

Under normal circumstances, perception runs very fast and seemingly automatic. In just a few ms, we go from sensory features to perceiving objects. This fast time course does not only apply to general perceptual aspects but also to what we call higher-level judgements. Inspired by the study on ‘very first impressions’ by Bar, Neta, and Linz (2006, Emotion, 6 , 269) the current research examined the speed and time course of three aspects of the aesthetic experience, namely beauty, specialness, and impressiveness. Participants were presented with 54 reproductions of paintings that covered a wide variety of artistic styles and contents. Presentation times were 10, 50, 100 and 500 ms in Experiment 1 and 20, 30 and 40 ms in Experiment 2. Our results not only show that consistent aesthetic judgements can be formed based on very brief glances of information, but that this speed of aesthetic impression formation also differs between different aesthetic judgements. Apparently, impressiveness judgements require longer exposure times than impressions of beauty or specialness. The results provide important evidence for our understanding of the time course of aesthetic experiences.
