Age and gender differences in solutions to hypothetical social problems

One hundred and twenty preschoolers and 77 kindergartners individually were administered a measure of social problem-solving. This measure consisted of five stories in which a protogonist sought to acquire an object from a same- or different-age or same- or different-sex target. Age differences in the numbers and types of strategies were few. However, kindergarteners showed greater flexibility in strategy sequencing. Prosocial strategies were more often directed to older targets; agonistic strategies were more often directed to younger targets. Girls suggested more prosocial strategies when girls sought an object from bay targets. Given the results it is suggested that flexibility is social problem-solving and attention to target characteristics should be included in future social problem solving training programs.     

Resistance to punishment as a function of intensity and frequency of prior punishment experience

Rats with a history of intermittent punishment have been found to persist in the face of continuous punishment. It was predicted from an extension of frustration theory to punishment that increasing the intensity or frequency of intermittent punishment would increase persistence to high fear elicited by continuous punishment. Two experiments, employing 310 rats, verified this prediction for both intensity and frequency manipulations but indicated rather narrow boundary conditions for their effects.     

Different memory functions for consonants and vowels

Different memory functions were obtained for consonants (C) and vowels (V) in a serial recall task. In general, the most recently heard vowels in a sequence were easier to recall than the most recently heard consonants. This effect was observed for auditorily presented sequences of CV or VC syllables, but was not observed for visually presented stimuli. The results were explained in terms of a limited capacity acoustic storage in which vowels are preserved longer than consonants. Retrieval of the last vowels from this storage was presumed to cause the vowel recency effect.     

Attitudinal qualities relating to the strength of the attitude-behavior relationship

A study was conducted to examine the relation between each of several attitudinal qualities and attitude-behavior consistency. Subjects' attitudes toward volunterring to participate in psychological research were assessed. The number of experiments in which each subject volunteered to participate was employed as the measure of behavior. Attitude-behavior consistency was significantly related to (1) the amount of direct experience upon which the subject's attitude was based (specifically, the number of experiments in which the subject had previously participated), (2) the degree of certainty with which the attitude was held, and (3) how well-defined the subject's attitude was, as measured by the width of his latitude of rejection. These three attitudinal qualities were significantly intercorrelated, suggesting that direct experience with an attitude object may produce an attitude that is both better defined and more confidently held than an attitude formed through more indirect means.     

The effects of increasing familiarity on infants' reactions to adult strangers

The influence of the presence and novelty of an adult stranger on the reactions of 12-mo-old infants was investigated. Subjects were placed near their mothers in a room containing a new toy and either the same, a different, or no adult stranger for 8 4-min trials. Results indicated that the Same-Adult Group spent more time near the adult, less time near and touching their mothers, and more time near and touching the toys than the Different-Adult Group. These trends emerged as the trials progressed, and evidenced the Same-Adult Group's growing familiarity with the adult. The No-Adult Group spent less time near or touching their mothers and more time near or touching the toys than the Different-Adult Group, but did not differ from the Same-Adult Group on these responses. The findings suggest that fearful or cautious reactions to adult strangers disappear rapidly as the adult becomes familiar and point to the value of studying the process whereby the infant becomes familiar with new people.     

Generality of persistence: The role of stimulus and response factors in persistence to punishment

Previous research has shown that intermittent punishment of a response increases its persistence to continuous punishment and that intermittent punishment training in one situation produces persistence to continuous punishment in other situations. Experiment 1 showed that as long as the instrumental response and punishing stimulus were held constant from intermittent to continuous punishment marked differences between these situations had no decremental effect on persistence. Experiment 2 showed that intermittent punishment training of one response resulted in substantial persistence to continuous punishment of a different and apparently incompatible response and that such response change had no more than a marginal effect on persistence. The results were seen as requiring some revision to the traditional conditioning-model interpretation of persistence to punishment.     

The influence of novelty and complexity on exploratory behavior in 12-month-old infants

This study investigated the influence of the novelty of the environment and the novelty and complexity of the objects (toys) it contained on the exploratory behavior of 12-month-old infants. Each infant was given a choice between novel and familiar toys located in two adjacent rooms (toy rooms). The novelty of the objects was manipulated by allowing the infants to play with one set of toys during a 5-min familiarization trial prior to the choice trial. The novetly of the environment was manipulated by allowing some infants to see, enter, and remain in the toy rooms during the familiarization trial. Finally, the complexity of the objects was manipulated by varying the number of familiar and novel toys; some Ss had four toys in each set (complex array) and some had only one (simple array). The results indicate that all three factors influenced the infants' exploratory behavior. Ss first approached, and spent more time manipulating, the novel than the familiar toys; they spent more time in the toy rooms if they were novel; and they spent more time manipulating the complex array of toys than the simple array.     

One answer to the demand for accountability: Selection utility as an investment decision

An examination of selection utility models demonstrates that they bear a considerable resemblance to capital budgeting models well established in the finance literature. Five applications of capital budgeting to selection utility are suggested and discussed. Capital budgeting concepts are recommended as a rich source of further practical and theoretical development of selection Utility models.     

Handedness and sex differences in hemispheric asymmetry

A study was designed to assess the contributions of the factors of sex and familial history to cerebral dominance, where cerebral dominance was inferred from laterality on a dichotic listening task. The 144 subjects were selected from a larger sample on the basis of handedness, sex, and familial history of sinistrality, and tested on a task involving the dichotic presentation of CV syllables. Analysis of the data indicated that in female subjects, the presence of familial sinistrality increased the likelihood that they present atypical left-ear superiorities, while in males the converse was the case. Moreover, there was a significant sex difference overall, such that males were more clearly lateralized than females. A review of other dichotic listening studies provided support for the reliability of this sex difference for dichotic tasks using verbal material. A review of the clinical literature indicated that the hypothesis of a sex difference is at least tenable and merits further investigation. However, the possibility that there is a sex difference in the cognitive strategy used in dichotic listening cannot be ruled out.     

Is dissonance phenomenologically aversive?

This study examined whether dissonance is, phenomenologically, an aversive state. Experimental subjects were induced to write counterattitudinal essays under a high-choice condition. One group of subjects was led to believe that a pill, which they had just taken in the context of a separate experiment, would cause them to feel pleasantly excited. A second group was led to believe that the pill would make them feel tense. A third group was given no information about the pill's potential side effects, while a fourth group expected to have no side effects at all. In this last condition, the results yielded the usual dissonance effect: subjects stated attitudes more congruent with the essay than did subjects in a survey control condition. When subjects were given an opportunity to attribute their arousal to an arousing, but nonaversive pill (i.e., the pleasant excitement condition), this effect was unchanged. In contrast, when subjects could attribute their arousal to an aversive pill (i.e., in the tensè and the no information conditions), this effect was virtually eliminated. These results are consistent with the notion that dissonance is an aversive state and that subjects will seize, when possible, an external attribution for this state.     

Attentional biases and the right-ear effect in dichotic listening

Most dichotic listening experiments permit subjects to deploy attention in any way they choose. We argue that this adds uncontrolled variance to the observed right-ear advantage. In the first experiment, more robust laterality effects were obtained in an identification task with focused than with divided attention. Such differences were not found in the second experiment, when a detection procedure was used. Virtually all the laterality effect observed in the second study could be attributed to subjects who were biased attenders, in the sense that they exhibited more intrusions from the right ear to the left than vice versa. However, rather than indicating that laterality effects are simply attentional bias, this effect can be attributed to an asymmetry of perceptual discrimination.     

Locus of control,field dependence and the conditions arousing objective vs subjective self-awareness

Observations of persons engaged in quasievaluative situations revealed that the greater amounts of body movement characterized as tension reducing were exhibited by persons holding internal control as opposed to external control expectancies. Conceptualizing situations as varying in the degree to which they allow one to become task involved (subjective self-awareness) or self-conscious (objective self-awareness) it was hypothesized that the latter would be more disruptive to internals, the former to externals. Body movement exhibited during introspection and personal reminiscence supported this hypothesis though no support was found in another task involving the completion of moral dilemma stories. In the latter task field dependent subjects proved to be more affected by self-awareness conditions, writing more normative stories when cues for objective self-awareness were more prominent.     

Immediate memory span, recognition memory for subspan series of words, and serial position effects in recognition memory for supraspan series of verbal and nonverbal items in Broca's and Wernicke's aphasia

Four Broca's aphasics, four Wernicke's aphasics, and four matched controls were investigated on three verbal and one visual short-term memory tasks. Experiment 1 considered memory span and subspan recognition memory for verbal items and Experiment 2 assessed serial position effects in supraspan verbal recognition memory. The Broca's aphasics demonstrated verbal memory deficits, which could not be attributed to linguistic disturbances, while the verbal memory deficiencies seen with the Wernicke's aphasics could be regarded as secondary to linguistic defects. In Experiment 3, where visual recognition memory was investigated, only the Broca's aphasics showed deficient performance. The wider context of deficient mnemonic performance in aphasia is discussed.     

Patterns of cerebral organization

An analysis of the concurrent incidence of aphasia and spatial disorder in 270 patients with unilateral brain damage suggests that the two functions are statistically independent. These data can also be used to estimate the distribution of left, right, and bilateral representation of linguistic and spatial functions in the population. In right-handers, sex affects the pattern of cerebral asymmetries, while the familial history of sinistrality has a stronger effect on the pattern of cerebral asymmetries in left-handers. These findings suggest that complementary specialization exists only as a statistical norm: It is suggested that differences in complementary and noncomplementary specialization may underlie individual differences in cognitive skills.     

A dissociation of right and left hemispheric effects for recognizing emotional tone and verbal content

Emotionally intoned sentences (happy, sad, angry, and neutral voices) were dichotically paired with monotone sentences. A left ear advantage was found for recognizing emotional intonation, while a simultaneous right ear advantage was found for recognizing the verbal content of the sentences. The results indicate a right hemispheric superiority in recognizing emotional stimuli. These findings are most reasonably attributed to differential lateralization of emotional functions, rather than to subject strategy effects. No evidence was found to support a hypothesis that each hemisphere is involved in processing different types of emotion.     

Dissonance and self-perception: An integrative view of each theory's proper domain of application

The literature concerning the controversy between dissonance and selfperception theories is reviewed. It is proposed that the two theories be regarded not as “competing” formulations but as complementary ones and, furthermore, that each theory is applicable only to its own specialized domain. Self-perception theory, it is suggested, accurately characterizes attitude change phenomena in the context of attitude-congruent behavior and dissonance theory attitude change in the context of attitude-discrepant behavior. Attitude-congruent is defined as any position within an individual's latitude of acceptance; attitude-discrepant as any position in the latitude of rejection. An experimental test of these notions produced confirming evidence. Subjects who were given an opportunity to misattribute any potential dissonance arousal to an external stimulus did not change their attitudes, relative to low choice subjects, if they were committed to endorsing a position in their latitude of rejection. If the commitment concerned a position in the latitude of acceptance, however, these subjects did exhibit attitude change relative to low choice subjects.     

Further evidence for meaning change in impression formation

Hamilton and Zanna (Journal of Personality and Social Psychology, 1974, 29, 649–654) demonstrated that the meaning of an attribute as rated on connotatively related scales changed as a function of context desirability. This finding was viewed as supporting a meaning change interpretation of context effects in impression formation. Kaplan (Memory and Cognition, 1975, 3, 375–380, Exp. 1) found that similar changes also occurred on scales unrelated in meaning to the test attribute and argued that changes on both kinds of scales were due to halo effects produced by the contexts. Controlling for possible scaling artifacts, the first experiment reported here showed that substantially greater changes occurred on related than on unrelated scales. Kaplan (1975, Exp. 2) also found that the magnitude of context-induced differences in judgments of trait likability was not increased by creating contexts denotatively related to the test attributes. Adding measures of connotative meaning, the second experiment in this paper showed that substantially greater context-induced changes did occur on related meaning scales and, in contrast to Kaplan, on trait likability for the denotatively related contexts. The results of each experiment are consistent with a meaning change position but would not be expected on the basis of the halo effects model.     

Correspondence and mediational properties of the Fishbein model: An application to adolescent alcohol use

The generalizability of the Fishbein model for behavior prediction was extended to a new field behavior, alcohol drinking by adolescents. The model's two components (i.e., attitudes and normative beliefs) varied in their predictive importance depending on the behavior's situational context. Following this field demonstration, two issues related to properties affecting the model's predictive effectiveness were investigated. First, it was found that the predictability of alcohol-drinking intentions (BI) declined when attitudes (A_act) and normative beliefs (NB) did not correspond with BI in terms of alcohol type (beer, liquor, or wine) and drinking situation (home, party, or pub). A second experiment tested the hypothesis that exogenous variables (those other than A_act and NB) would have a direct influence on BI. A comprehensive test was provided within the context of Jessor's multivariate predictive system for adolescent alcohol use. Present data indicate only a marginal increase in explained variance occurred when applying this system, thereby generally indicating the sufficiency of the Fishbein model's two components.
