Defensive burying of aversive fluids in rats: The possible role of odor

Defensive burying of flavored fluids paired with lithium chloride injections was examined. Rats showed little inclination to bury conditioned saccharin or salt solutions (Experiments 1 and 2). However, they buried tabasco sauce or dilute milk solutions readily (Experiment 3). It was hypothesized that the amount of olfactory stimulation provided by a solution may determine whether a rat engages in burying. This hypothesis received support in a final experiment which demonstrated that rats readily buried an arbitrarily selected odorous solution which was previously paired with lithium chloride. Thus the present experiments begin the process of identifying the circumstances under which burying does and does not occur.     

On the nature of processes governing defensive burying of aversive flavors and odors in rats

Four experiments are reported which investigated the processes which contribute to the failure of rats to bury fluids that have acquired aversive properties through pairings with lithium chloride toxicosis. Fluids that failed to provide strong olfactory stimulation were avoided but not buried. These solutions, however, produced higher order conditioning of odor-bearing solutions which were buried readily. Various control experiments indicated that these effects depended upon the odorous qualities of the stimulus and not upon simple novelty effects or changes in gustatory stimulation. These data indicate that the inability of aversive gustatory cues to produce burying reflects a constraint on motivational or S-R learning processes.     

Determinants of social perception in a naturalistic setting

Based upon the assumption that personality traits exist more in the eye of the observer than is actually reflected in the actions of the actor, Jones and Nisbett have proposed that a negative relationship exists between familiarity with an actor's behavioral history and the tendency to attribute traits to that individual. An alternative viewpoint is suggested by the present research. Members of a college fraternity attributed more personality traits to themselves than were attributed to them by their fellow members. In addition, the fraternity members tended to offer more dispositional attributions to other members with whom they were more familiar. Furthermore, evidence is presented that is suggestive of the validity of these attributions. It is concluded that the attribution of personality traits provides attributors with information that is both veridical and useful in guiding social interactions.     

Defensive burying of aversive fluids in rats: The effects of peripheral anosmia

Three experiments were conducted in order to determine the role of olfactory stimulation in defensive burying of aversive fluids in rats. The results revealed that zinc sulfate-induced anosmia eliminated burying of fluids paired with lithium chloride as well as an inherently aversive solution. This occurred despite the fact that the rats avoided consuming them. These data indicate that defensive burying of aversive fluids is governed by olfactory stimuli and confirms an earlier report, which indicted that burying does not occur in response to aversive gustatory stimuli.     

The expectancy model in the analysis of occupational preference and occupational choice

The differences between the factors related to occupational preference and occupational choice were explored for upper-division college students from business and psychology classes. The results strongly supported a valance-instrumentality-expectancy model in the context of occupational choice. Occupational preference was primarily a function of occupational valence, the multiplicative relation between the outcome valences and the instrumentalities of the occupations for these outcomes. Occupational choice was primarily a function of the force to choose an occupation, the multiplicative relaitonship between occupational valence and the expectancy of attaining an occupation and the expected costs of attaining an occupation.     

Need for uniqueness,self-schemas,and thought as moderators of the false-consensus effect

L. Ross and his colleagues (L. Ross, D. Greene, & P. House, 1977, Journal of Experimental Social Psychology, 32, 880–892) have demonstrated the tendency for people to expect peer similarity in behavior, termed the “false-consensus” bias. The present study was concerned with factors that might affect the generality of this bias. Specifically, we looked at the impact of level of need for uniqueness (C. R. Snyder & H. L. Fromkin, 1977, Journal of Abnormal Psychology, 5, 518–527), existence of a self-schema (H. Markus, 1977, Journal of Personality and Social Psychology, 35, 63–78), and thought on expectations of peer similarity. It was predicted that thought would polarize the estimates of high and low N Uniq individuals in opposite directions, but only when the individual possessed a self-schema along the relevant behavioral dimension. The results for behaviors reflecting independence supported this prediction. Discussion centered around limits of the false-consensus bias, along with consideration of the complexities involved in the link between availability factors and interpersonal judgments.     

Causal attributions for behaviors consistent or inconsistent with an actor's personality traits: Differences between those offered by actors and observers

The present research was designed to investigate differences in the attributions offered from the actor's perspective and the observer's perspective. It was predicted that causal attributions for behaviors inconsistent with an actor's personality traits would be more situational when offered from the actor's perspective than when offered from the observer's perspective. In contrast, it was predicted that causal attributions for behaviors consistent with an actor's personality traits would be more dispositional when offered from the actor's perspective than when offered from the observer's perspective. Consistent with these hypotheses, extraverts explained introverted behaviors and introverts explained extraverted behaviors more situationally from the actor's perspective than from the observer's perspective. Furthermore, extraverts explained extraverted behaviors and introverts explained introverted behaviors more dispositionally from the actor's perspective than from the observer's perspective. These differences in the attributions offered by actors and observers were attenuated but not eliminated when attributors had access to useful situational information with which to apply the discounting principle.     

The development of orientation categories between 2 and 4 months of age

Recent research has indicated that infants are capable of responding to stimuli in a manner indicating that they categorize them. Infant perception of orientation was examined within a framework of categorization. In one experiment, it was shown that 4-month-old infants generalized habituation from one range of oblique grating stimuli to another, consistent with the interpretation that any two oblique stimuli were perceived as more similar than a vertical and an oblique. Four-month-old infants' generalization was not due to a simple inability to discriminate between obliques (Experiment 2) so the results of Experiment 1 reflect in large part true categorization behavior and not categorical perception. Results for 2- and 3-month old infants suggest that "vertical" serves as a reference stimulus in infant orientation perception such that gross distinctions between vertical and nonvertical precede the development of the "oblique" category. The category boundary between oblique and vertical did not successfully predict better between-than within-category discrimination in 4-month-old infants (Experiment 3) under the conditions of these experiments.     

Self-verification processes: How we sustain our self-conceptions

It is proposed here that individuals use their social interactions as opportunities to verify and confirm their self-conceptions. In a series of empirical investigations, three unique strategies of self-verification are examined. In Investigation I, participants were more likely to seek social feedback when they believed that it would confirm their self-conceptions. In Investigation II, participants elicited reactions from their interaction partners that confirmed their self-conceptions, especially when they suspected that their interaction partners' appraisals might disconfirm their self-conceptions. In Investigation III, participants preferentially recalled social feedback that confirmed their self-conceptions. Thus, within each of three distinct phases of the social interaction, people sought to verify their self-conceptions. The interplay of different strategies of self-verification and the conditions under which they will occur are discussed.     

The interaction of semantic memory with storage and retrieval processes

A procedure for separating storage from retrieval (R. Chechile & D. L. Meyer, Journal of Mathematical Psychology, 1976, 14, 430–437) lead to the conclusion that memory development involves changes in both storage and retrieval. Nevertheless, these changes resulted from the interaction of storage and retrieval mechanisms with the age-related elaboration of the semantic memory system. This study shows that the memory improvement with age, between kindergarten and second grade, vanished when the meaningfulness of the materials were equated. The most plausible interpretation of the results is the hardware invariance hypothesis. According to that hypothesis, the memory apparatus for information processing is constant across ages, but the hardware is used more effectively if there is a better-developed semantic memory system.     

Achievement orientation,attainment values,and women's employment

This study examines age variance in the relationship of women's achievement needs and values to their participation in paid employment. The study group is a cross-sectional, nonprobability sample of 1120 women, ages 22–64, who contacted the Center for Continuing Education of Women at a major midwestern university. Three findings predominate: (1) Compared to general achievement orientation, the specific values attached to attainment through career and family are stronger predictors of employment status. (2) Degree of participation in paid employment is related positively to career values, and negatively to family values. (3) Career values, alone, are the best predictors of employment status among women aged 45–64, while a combination of career and family values best predicts employment among women aged 22–34 and 35–44. The findings suggest that women's labor force participation is partially a function of the interaction between career and family task demands and values.     

Effect of positive,negative, and mixed occupational information on cognitive and affective complexity

A series of concentrated research studies over the past 8 years has significantly demonstrated that cognitive complexity in the vocational realm is positively related to congruence or appropriateness of vocational choice. Moreover, research has shown that introducing occupational information significantly reduces, rather than increases, cognitive complexity. The results of the study reported here relate to changes in cognitive complexity as a function of the type of occupational information introduced, namely, information with respect to the advantages of occupations; the disadvantages of occupations, or a combination of positive and negative features of occupations. Our results clearly demonstrated that while positive occupational information alone leads to greater simplicity, negative or mixed information significantly retards the trend toward greater simplicity. Results are discussed from both theoretical and practical perspectives, especially with reference to the typical occupational information provided in routine vocational counseling.     

Self-esteem and cognitive consistency effects on self-other evaluation

Reactions to bogus evaluations of one's self, either positively or negatively discrepant from one's own self-evaluation, were investigated among subjects differing in self-ideal discrepancy. All subjects exhibited greater acceptance of the source of favorable information than the source of unfavorable information, and changed their self-evaluation more toward the favorable than unfavorable position. However, among low self-ideal discrepancy subjects, the change in self-evaluation was accompanied by a similar change in friend evaluation, thereby maintaining their standing in relation to this friend after receiving either positive or negative evaluations. In contrast, high discrepancy subjects downgraded the friend more and upgraded the friend less than themselves, thereby enhancing their relative standing as a result of the feedback. These findings indicated that defensive or self-enhancing effects on self-evaluation processes are determined by self-ideal discrepancy.     

Personality correlates of occupational status according to Holland types

The present investigation sought to identify personality correlates of occupational status. Because occupational status is a direct function of occupation, the relationship between personality and status was examined both within and across occupational groups using Holland's 1973 typology. Four two-way analyses of covariance of 16PF (Sixteen Personality Factor Questionnaire, Form A) second-order personality factors were performed using data from 175 employed adult males. No single personality factor was associated with status across occupational types. Among Social occupations, the low-status group had higher Extraversion and lower Anxiety scores than the high-status group. In general, the relationship between personality factors and occupational types provided additional confirmation of Holland's theory using an employed adult sample.     

Attributions of causality and reactions to uncontrollable outcomes

The experiment tested the hypothesis that the stress experienced by a person who is unable to control aversive stimulation is not a function of lack of control per se, but of the attribution of causality that (s)he makes for failure to exert control. Subjects were given a problem-solving task, and were told that they could prevent aversive noise bursts by correctly solving the problems. Subjects then received false feedback that they had done either well or poorly on the problems. In addition, failing subjects received information that led them to attribute their performance either to their own lack of ability or to situational factors (task difficulty). Subjects who attributed their failure to their own incompetence felt considerably more stress than subjects who made situational attributions. In fact, the latter subjects experienced no more stress than subjects who were successful in controlling the stimulation. Surprisingly, subjects whose attributions for performance led them to feel personally incompetent performed better than the remaining subjects both on problems administered in the same situation, and on problems administered in a new and different situation. The implications of the results for future helplessness studies and for the learned helplessness model were discussed.     

Academic achievement: An examination of Holland's congruency,consistency, and differentiation predictions

This investigation tested three predictions derived from Holland's (1973) theory of vocational development regarding academic achievement. Groups of 392 male and 424 female entering college freshmen were typed using the Strong-Campbell Interest Inventory and were categorized in terms of congruency, consistency, and differentiation. Freshmen with congruent college major choices or with definite majors but indefinite Holland orientations enjoyed greater academic success than students who specified incongruent choices or no definite major choice. Students with personality codes of high or low consistency outperformed students with moderately consistent codes. Freshmen males with differentiated personal orientations achieved higher grade point averages than males having nondifferentiated personality profiles. For females, differentiation was not significant. In all sex comparisons female trends paralleled male trends and females generally outperformed males. Implications for vocational development and counseling were discussed in the context of Holland's theory.     

The fantasy-reality distinction in televised violence: Modifying influences on children's aggression

Fifth-grade and kindergarten boys and girls were exposed to a violent televised episode that was introduced as a fictional portrayal (fantasy condition) or as a news broadcast (reality condition). Additional groups were given no information (no-instructional-set condition) about the violent stimulus or were not exposed to the violent episode (no-TV condition). Aggressive responses and helping responses were recorded immediately following exposure. Boys were most aggressive in the reality and no-TV conditions. They were less aggressive in the noinstructional-set condition and least aggressive in the fantasy condition. In almost direct contrast, girls were most aggressive in the fantasy and no-instructional-set conditions and least aggressive in the reality and no-TV conditions. A posteriori analyses of this interaction effect revealed that girls were less aggressive than boys in the no-TV condition and in the reality condition, but not in the fantasy condition nor the no-instructional-set condition. These effects held for both older and younger children.
