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.     

Effects of a school mental health project: A one-year follow-up

Matched samples of children who had (Terminators) or had not (Nonterminators) successfully participated in a school-based project for the early detection and treatment of school maladaption were compared on teacher ratings of adjustment with a control sample having no prior program contact. Terminators were found to have significantly more positive school adjustment ratings than Nonterminators and Controls, both five and 12 months after their final program contact. These data support the conclusion that the program has positive consequences for children in the primary grades which generalize to new classroom settings and remain stable over time. The absence of adjustment differences between Nonterminators and Controls suggests the importance of developing alternative approaches for those not benefiting from the program.     

The effect of training procedures on the overlearning reversal effect in young children

The performance of 80 preschool children on a reversal problem was studied as a function of amount of training and type of training procedure used during acquisition and reversal. In the extinction phase of reversal learning, subjects given a correction procedure during the reversal problem made fewer perseverative errors than subjects given noncorrection. In the reversal midplateau phase of reversal learning, overtraining facilitated reversal learning for subjects receiving noncorrection during the acquistion problem, but not for subjects receiving correction. A shift in training procedure between acquisition and reversal increased the number of subjects who reached criterion immediately after perseveration. Since these results are difficult to explain in terms of traditional learning theories, an alternative response-switching strategy explanation was proposed.     

The effects of relaxation instructions on drinking behavior in the presence of stress.

Previous research indicates that antecedent stress is associated with increased alcohol consumption. The present study examined the influence of different treatments following threatened exposure to a public speaking situation on both drinking style measures and amount consumed in an ad lib drinking assessment session. The treatments included relaxation instructions, a sensitization or stress-enhancing treatment, and an attention-refocusing or neutral control. Significant differences in poststress drinking rates and amount consumed between the stress-relaxation and stress-sensitization groups were found. The data indicate that relaxation is an effective procedure for attenuating the impact of stress on quantity and style of drinking.     

School-related problems of Mexican-American adolescents

An attempt is made to explain certain selected aspects of the school problems of some Mexican-American adolescents by an analysis of major cultural themes. The data presented suggest that for some Mexican-American adolescents, school has at least the following four meanings: (1) a place where teachers are frequently perceived and treated as authority figures similar to their fathers and, therefore, are targets of rebellion; (2) a place lacking strict external prhibition of encounters with the opposite sex; (3) a public arena of activity where one can bring honor or shame to one's family: and (4) an institution which expects participating individuals to value individual competition and success. Finally, these problems are discussed with respect to problems that Mexican-American female adolescents have in direct expression of anger.     

Objective self awareness and self esteem

Based on a theory of objective self awareness three experiments were conducted with undergraduates to test the hypothesis that self-focused attention can alter self esteem levels. In Experiments I and II subjects were exposed either to the sound of their own voices or to the sound of another's voice, and while listening to the tape-recording they filled out a self esteem measure. Consistent with the theory, subjects whose attention was focused upon themselves by means of exposure to their own tape-recorded voices showed lower self esteem than subjects who heard another's voice. The impact of the self awareness manipulation on self esteem was greatest when it was first introduced. In Experiment III the variable of positive-negative feedback on a fictitious personality trait was added to the self-focused attention variable. An interaction resulted such that self-focused attention lowered self esteem given negative feedback, while there was a tendency toward the opposite result given positive feedback.     

A simple instrument for measuring vocational interests based on Roe's classification of occupations

A vocational interests inventory-“Ramak”-based on Roe's (1956) classification of occupations was constructed. It consisted of 72 names of occupations. Equivalent-test reliability of 0.76 was achieved. The inventory was validated on working samples and by the structure of intercorrelations. The advantages of this inventory are discussed.     

Stimulus learning versus response learning in a discriminated punishment situation

The suppression of bar pressing under two kinds of conditions was compared. Under one condition the response was occasionally punished by shock in the presence of a signal. Suppression to the signal was quickly acquired, indicating rapid learning about the signal-shock relationship (stimulus learning). Under the other condition the response was occasionally punished in the presence of the signal but additional free shocks were given in the absence of the signal. The slow acquisition of suppression found in this case indicated that there was, at best, only gradual learning about the response-shock relationship (response learning).     

Operationalizing the effect of the group on the individual: A self-attention perspective

The effect of the group on the individual is considered from the perspective of self-attention theory. It is proposed that group members will become more self-attentive, and thus become more concerned with matching to standards of appropriate behavior, as the relative size of their subgroup decreases. A simple algorithm, termed the Other-Total Ratio, is presented which numerically describes this effect of the group on the individual. An analysis of group effects on individuals' self-attention supports this perspective, as do analyses of the results of 42 previous studies in four other areas (conformity, prosocial behavior, social loafing, and antisocial behavior). This orientation to the effect of the group on the individual is linked to recent developments in self-attention theory and compared to Latané's social impact theory.     

Evidence for a developmental shift in the basis for memory organization

Using a false recognition procedure, either with or without instructions to facilitate Synonym or Antonym encoding, 128 second- and sixth-grade boys and girls were tested. The results indicated that there were no grade or sex differences in generalization errors to synonyms or antonyms under neurtral learning instructions, but that facilitative instructions interacted with grade level. Under instructions to facilitate synonym encoding, second graders showed a marked increase in synonym errors. On the other hand, under instructions to facilitate antonym encoding, sixth graders showed an increase in antonym errors. In addition, association strength was directly related to the magnitude of the generalization errors in both grades. The results are discussed in terms of age-related shifts in the basis underlying the organization of verbal memories.     

A developmental study of choice reaction time: the effect of two forms of stimulus degradation on encoding.

To assess the effects of environmental enrichment, 156 normal, full-term institutionalized infants were randomly assigned to Group I (30 min per day of supplementary vestibular stimulation), Group II (30 min per day of supplementary vestibular-plus-verbal stimulation), or Group III (untreated controls). Stimulation began at about the age of 12 days and continued until the children were adopted, approximately 6 weeks later. Children were assessed at regular intervals on the Gesell Developmental Schedules, until the age of 27 months. Group comparisons revealed no significant treatment effects.     

The self-serving attributional bias: Beyond self-presentation

An experiment was conducted to provide empirical support for the notion that asymmetrical causal attributions for favorable and unfavorable outcomes result from a self-serving attributional bias that occurs independently of self-presentational concerns. Subjects did either well or poorly on an ego-involving test for which their performance, attributions, and evaluations of the test were either public or private. A pattern of self-serving responses for subjects' attributions and evaluations of the test was found in the private conditions, thus providing evidence of the influence of outcome favorability on individuals' perceptions of causality. Theoretical and practical implications of these finding are discussed and suggestions for future research are offered.     

Role played self-disclosure as a function of liking and knowing

Subjects identified persons from their own lives whom they liked and knew to varying degrees. At a later session, subjects role-played a self-disclosing conversation with each identified person. Verbal behavior was recorded and analyzed with respect to the personalness of disclosure. Analysis of variance results for both self-report and observational measures show significant effects for liking and knowing on personal, but not impersonal, self-disclosure. The pattern of results over all dependent measures indicates that liking has a more specific effect on personal disclosure than does knowing, but that liking and knowing do not differ in relative control over impersonal disclosure. A correlational analysis involving subjects' perceptions of the experimental situation and the dependent disclosure measures supported this interpretation.     

The effect of monetary incentives on backward digit span performance

In order to determine if monetary-incentive effects, particularly the detrimental effects of such incentives on human learning and performance, might be mediated by anxiety, 52 college students were administered six backward digit trials in a preexperimental, baseline phase and six trials in an experimental, test phase. Of the 52 subjects, 26 were paid 50 cents following each correct recitation of a backward digit series during the test phase. The remaining 26 were unpaid control subjects. Results showed that the rationale for the study was correct because state anxiety was indeed negatively related to backward digit span performance as previous research had shown, but the offer of reward did not elevate state anxiety scores and, more importantly, the offer of reward led to a significant improvement in backward digit span performance—an effect which is the opposite of what would be predicted by the anxiety hypothesis. The reward effects of theoretical interest in planning this research were those facilitating and detrimental effects that are produced by offering elementary, high school, or college students small amounts of money (typically from $1 to $3) as a superfluous inducement to participate in a study of human learning or performance. The results of this study discredit any explanation of such reward effects which attributes the effects to reward-induced anxiety.
