THE USE OF POSITIVE AND NEGATIVE REINFORCEMENT IN THE TREATMENT OF ESCAPE-MAINTAINED DESTRUCTIVE BEHAVIOR

We identified 3 clients whose destructive behavior was sensitive to negative reinforcement (break from tasks) and positive reinforcement (access to tangible items, attention, or both). In an instructional context, we then evaluated the effects of reinforcing compliance with one, two, or all of these consequences (a break, tangible items, attention) when destructive behavior produced a break and when it did not (escape extinction). For 2 clients, destructive behavior decreased and compliance increased when compliance produced access to tangible items, even though destructive behavior resulted in a break. For 1 client, extinction was necessary to reduce destructive behavior and to increase compliance. Subsequently, when the schedule of reinforcement for compliance was faded for all clients, destructive behavior was lower and fading proceeded more rapidly when compliance produced multiple functional reinforcers (i.e., a break plus tangible items or attention) and destructive behavior was on extinction. The results are discussed in terms of the effects of relative reinforcement value and extinction on concurrent operants.     

Filipino Personality Structure and the Big Five Model: A Lexical Approach

ABSTRACT In lexically based studies, we derived Filipino personality dimensions and related them to the Big Five model. In Study 1, Filipino high-school and college students (N= 629) rated themselves on a near-comprehensive list of 861 Filipino (Tagalog) trait adjectives. In Study 2, Filipino high-school and college students (N= 1,531) rated 280 markers of dimensions identified in Study 1. Some students (n= 473) also completed the NEO Five-Factor Inventory. Seven comparable Filipino dimensions were identified in factor analyses in the two studies. We concluded that the dimensions we labeled Concern for Others (vs. Egotism), Conscientiousness. Gregariousness, and Intellect were quite similar to Big Five Agreeableness, Conscientiousness, Extraversion, and Intellect, respectively. The Filipino Self-Assurance dimension was most similar to Big Five Neuroticism. The Filipino Temperamentalness dimension was more complex in Big Five terms, overlapping Agreeableness, Conscientiousness, and Neuroticism. A final Filipino factor resembled a Negative Valence or Infrequency dimension. More than five factors had to be extracted to obtain Philippine dimensions resembling all of the Big Five.     

Gender and Video Game Performance

We investigated potential gender differences in video game (pong) performance in university students. In Experiment 1 men (N = 16) performed significantly better than women (N = 16). Experiment 2 was similar to the first, but used 14 men and 14 women who were matched carefully on previous video game experience. In spite of the matching, results replicated those of the first experiment. In Experiment 3 we evaluated the effect of an audience (male, female, none) on pong performance in 42 men and 42 women. We also assessed trait competition anxiety (Sport Competition Anxiety Test scores), sex role identification (Bem Sex Role Inventory scores), and video game experience. Both genders showed significantly poorer performance when they played pong in the presence of a female audience. Overall, males outperformed females as in the first two experiments. Examination of individuals with low, medium, and high levels of sport competition anxiety and videogame experience reveals persistent gender differences in performance, seemingly independent of levels of anxiety and experience. In all three experiments, both men and women showed significant improvement in performance over trials.     

The impact of school emotional climate on student psychopathology

Reports of differences among schools in emotional and social climate were related to changes in behavioral and emotional problems and alcohol use in students who remained in these schools over a 2-year interval. Four dimensions of school climate were examined. School conflict and social facilitation were shown to be related to increases in childhood psychopathology, whereas student autonomy was not. Effects of academic focus were even stronger than those of conflict, in the sense of being independently related to more syndromes. School climate effects were examinedfor conditionality on student characteristics and for synergism, It was concluded that intervention to alter the school climate may promote the emotional and behavioral well-being of children and adolescents.This research was supported by NIMH Grants MH36971 and MH30906.

Sex-role orientation and intimacy status in men and women

Sex-role orientation based on combined t-ratio/median-split scoring of Personal Attributes Questionnaire data was investigated in relation to intimacy status in a sample of university alumini with an average age of 25 years. There was no significant sex difference in sex-role orientation or social status. As expected, androgyny was associated with the preintimate status in both men and women. Contrary to prediction, androgyny was also associated with the less intimate statuses of merger in men and pseudointimate in women; sex-typing was associated with the most intimate status in both sexes. All sex-typed individuals were involved in long-term, heterosexual partnership varying in level of intimacy.Part of this research was included in a presentation at the Annual Convention of the American Psychological Association, Montreal, September 1980. The author thanks Susan Krauss Whitbourne for providing advice and intimacy status ratings for this research.     

Reports of bodily change in anxiety,sadness, and anger

In a series of studies, retrospective reports were used to assess differences in physiological symptoms associated with three emotions: Anxious, Angry, Sad. Symptom awareness, as measured by scores on the Autonomic Perception Questionnaire and the Somatic Perception Questionnaire, was significantly greater for Anxious than for the other emotions; reports for Angry and Sad were quantitatively similar. Qualitative analysis showed a different pattern. Sad was characterized as involving a low arousal state, while Anxious and Angry shared several distinguishing symptoms, most notably cardiac symptoms and general restlessness. Predicted gender differences were also observed. Males and females did not differ in overall reported level of awareness, but did differ in their reports of the specific symptoms constituting that awareness.     

Stimulus-specific contrast effects during operant discrimination learning

In two experiments, pigeons' responding was equally reinforced in the presence of four line-orientation stimuli. Responding was then reinforced when only two of the four orientation stimuli were present; the remaining two orientations appeared during extinction. Response rates were often highest in the stimulus adjacent to the orientations presented during extinction and often lowest in that orientation adjacent to the orientations presented with reinforcement. These effects were stronger and more persistent when the stimuli were separated by a smaller angle, rendering the discrimination more difficult. These and other data suggest that discrimination training may not be accurately explained in terms of the simple effects of reinforcement and nonreinforcement associated with isolated stimuli, nor by accounts that depend upon stimulus generalization. Recent accounts of contrast that depend upon “emotionality” produced by nonreinforced responding or upon reinforcement-elicited responses are also difficult to apply to these data.     

Sex differences in attraction to infants: When do they occur?

Harlow (1971) observed that all-female college audiences responded to a pictured infant rhesus monkey with an “ecstasy response,” while males were “completely unresponsive,” and females in coeducational audiences “inhibited the ecstasy response,” explaining these differences in terms of innate sex differences. The present study compared college students' self-reported attraction to pictures of 15 infant and adult nonhuman primates under several conditions. Infant pictures were of two types: infants which were engaged in typical infant behaviors (Infant Behavior), and those which were not (Infant). Subjects made judgments in same- or mixed-sex groups and reported degree of attraction publicly or privately. Ratio scores were used to represent each subject's attraction to infant or infant-behavior pictures compared with his or her attraction to pictures of adults. There were no significant sex differences in attraction to infant or infant-behavior pictures, and sex did not interact with any other variable. However, situational variables significantly affected the response. Males as well as females reported greater attraction to infant and infant-behavior pictures when they viewed the pictures in same-sex compared with mixed-sex groups. Both sexes reported greater attraction to infant and infant-behavior pictures privately than publicly.     

Contrast effects in maintained generalization gradients

In Experiment I, pigeons were given equal reinforcement (variable-interval 1-min) for responding during randomized presentations of eight line-orientation stimuli. Then, only responding in the vertical orientation was reinforced. Stable generalization gradients soon formed and persistent behavioral and local (transient) contrast effects appeared. Local contrast effects were not a function of relative reinforcement frequency or of any other variable known to produce contrast. Instead, they were related to average response rates associated with each stimulus. Experiment II showed that local contrast effects represent increases and decreases in response rates relative to baseline responding, and that these effects are relative; a given stimulus might enhance responding during a subsequent presentation of one stimulus, but depress responding when followed by another. These data indicate that discrimination learning is not adequately described as the acquisition of excitatory properties by some stimuli and inhibitory properties by others. A more adequate account implies that stimuli exert both excitatory and inhibitory effects related to their value.     

The effect of frustrative nonreward on the attractiveness of the omitted reward

Two experiments were performed to test the hypothesis that omission of a previously received reward is followed by greater motivation to obtain that specific reward, as compared with the case where the reward had been present. In Experiment 1, experimental rats regularly received food rewards (R_a) at one goal, followed by a choice between food and milk (R_b). Control animals received the same choice without food preceding it. Reward magnitudes were manipulated so as to produce a preference for R_b, and additional forced trials were given each day to equalise experience of the two rewards. In the test phase both groups received trials with R_a present (R) or absent (N) at the first goal. The experimental Ss shifted their choice towards R_a on N trials; the controls did not behave differently after R and N. Experiment 2 was similar, except that R_a was milk and R_b food. The same effect of N on experimental animals was obtained. It is argued that the results are relevant to the double-runway ‘frustration effect’, and cannot be explained by existing theories of frustration.
