Student learning as the basis for reinforcement to the instructor

The present study reinforced the two instructors of two students with profound mental retardation first for the instructors' training behaviors, then for improved student learning in a multiple baseline across responses design. Reinforcement of the instructors' training behaviors increased their training behaviors, replicating the findings of previous studies, but had no effect on student learning. When the reinforcement for the instructors was instead made contingent upon student learning, the student learning improved and the instructors' high level of training behaviors was maintained. In addition, the instructors began to request training for themselves. These findings suggest that staff motivation programs for instructors might usefully base the reinforcers not only on the instructor's performance, but on the progress of their students.     

Development and validation of adolescent-perceived microsystem scales: Social support,daily hassles,and involvement

Developed and validated instruments for urban and culturally diverse adolescents to assess their self-reported transactions with family, peer, school, and neighborhood microsystems for the constructs of social support, daily hassles, and involvement. The sample of 998 youth were from schools in three Eastern cities with high percentages of economically disadvantaged youth. Data were collected before and after the transition to junior high school or to senior high school. Blacks constituted 26%, whites 26%, and Latinos 37% of the sample. Factor analyses confirmed and enhanced the hypothesized four-factor microsystem factor structure for support, hassles, and involvement; internal consistency and stability coefficients were consistent with these structures. In general, the microsystem factors were common across gender, ethnicity, and age. However, when group differences did occur on these demographic variables, they tended to validate the salience of microsystem specificity. In contrast to the total scores, the microsystem-specific factors yielded more meaningful and differential information with regard to demographic differences and the mediating processes across a school transition.     

Simulation study of a decision-making model of squash competition, phase one: The analysis of the protocol

This study aims at specifying some of the cognitive processes underlying decision-making in squash competition. More specifically, the study focuses on the strategy of the defending player (D) when chosing among three categories of preparation (total preparation for one particular event, partial preparation in favor of one event and absence of biased preparation). D is viewed as an information processing system (IPS) placed in a problem-solving situation, the problem being what decision to reach. The results obtained in a preceding investigation about the nature of the information processed by a player to anticipate and prepare for the opponent's shot in a real game setting, are used to determine a typical protocol of the behavior of D. The analysis of this protocol allows one to formally define (in Backus-Normal-Form) the problem space of D which is also D's internal representation of the task environment. From the problem space are derived (1) the problem behavior graph depicting the search of D through his problem space for a solution, and (2) the production system (a set of conditional statements, each expressing what to do under specific conditions) defining the logic of the search. The results of this first phase of the simulation study of a decision-making model of squash competition show that the cognitive strategy of D is based upon the use of a specific preformed algorithm. This algorithm could be stored in some long-term memory and activated by the current state of information in short-term memory. Finally, the proposed model also leads to the suggestion that the cognitive strategy of the performer may be influenced by a variety of factors such as the experience of the player, the time pressure, the expectancies, the performer's confidence in his predictions and the mistakes caused by incorrect predictions.     

Some effects of congenital spasticity on fundamental frequency

5 normal speakers and 5 speakers with congenital upper motor-neuron damage repeatedly spoke a three-work sentence stressing the first, second, or third words. Fundamental frequency was measured for each word and over each sentence. Analysis showed that the spastics' mean fundamental frequency was significantly higher than the normals', regardless of utterance. Also, spastics were more restricted in their prosodic maneuvering above this average fundamental frequency. Despite this finding, the spastics were capable of producing consistent stress patterns with normal variability.     

Perception of mind and dehumanization: Human,animal, or machine?

Dehumanization is reached through several approaches, including the attribute‐based model of mind perception and the metaphor‐based model of dehumanization. We performed two studies to find different (de)humanized images for three targets: Professional people, Evil people, and Lowest of the low. In Study 1, we examined dimensions of mind, expecting the last two categories to be dehumanized through denial of agency (Lowest of the low) or experience (Evil people), compared with humanized targets (Professional people). Study 2 aimed to distinguish these targets using metaphors. We predicted that Evil and Lowest of the low targets would suffer mechanistic and animalistic dehumanization, respectively; our predictions were confirmed, but the metaphor‐based model nuanced these results: animalistic and mechanistic dehumanization were shown as overlapping rather than independent. Evil persons were perceived as “killing machines” and “predators.” Finally, Lowest of the low were not animalized but considered human beings. We discuss possible interpretations.     

Sound attenuation and preferred music in the treatment of problem behavior maintained by escape from noise

We examined the extent to which different sounds functioned as motivating operations (MO) that evoked problem behavior during a functional analysis for two participants. Results suggested that escape from loud noises reinforced the problem behavior for one participant and escape from arguing reinforced problem behavior for the other participant. Noncontingent delivery of preferred music through sound‐attenuating headphones decreased problem behavior without the use of extinction for both participants. We discuss the results in terms of the abolishing effects of the intervention.

Attentional load associated with performing and stabilizing a between-persons coordination of rhythmic limb movements

This study addressed the issue of intentional stabilization of between-persons coordination patterns (in-phase/isodirectional and anti-phase/non-isodirectional) and the attentional cost incurred by the nervous system in maintaining and further stabilizing these coordination patterns. Five pairs of participants performed in-phase and anti-phase interpersonal coordination patterns in dual-task conditions (coordination+RT task). Results showed that: (1) isodirectional pattern (in-phase) was more stable than non-isodirectional pattern (anti-phase), (2) both iso- and non-isodirectional pattern were stabilized intentionally, (3) RT was lower for the isodirectional pattern (i.e., the most stable), and (4) attentional manipulation led to a trade-off between pattern stability and RT performance. These results suggest that performing between-persons coordination patterns incurs a central cost that depends on the coupling strength between the limbs. These findings are consistent with the previous studies in intrapersonal coordination.     

The effects of self-focused attention, performance demand, and dispositional sexual self-consciousness on sexual arousal of sexually functional and dysfunctional men

Sexually functional (N=26) and sexually dysfunctional heterosexual men with psychogenic erectile disorder (N=23) viewed two sexually explicit videos. Performance demand was manipulated through verbal instruction that a substantial genital response was to be expected from the videos. Self-focused attention was manipulated by introducing a camera pointed at the participant. Dispositional self-consciousness was assessed by questionnaire. Performance demand was found to independently inhibit the genital response. No main effect of self-focus was found. Self-focus inhibited genital response in men scoring high on general and sexual self-consciousness traits, whereas it enhanced penile tumescence in low self-conscious men. Inhibition effects were found in both volunteers and patients. No interaction effects of performance demand and self-focus were found. Subjective sexual arousal in sexually functional men was highest in the self-focus condition. In sexually dysfunctional men, subjective sexual response proved dependent on locus of attention as well as presentation order.
