Testing a Rebt Theory: The Effects of Rational Beliefs, Irrational Beliefs, and Their Control or Certainty Contents on the Functionality of Inferences: I. In a Social Context

This article presents two experiments that examine the validity of REBT's suggestion that contents do not influence the effect that rational and irrational beliefs (beliefs) have on the functionality of inferences (FI). Specifically, two role-playing experiments indicated that control and certainty contents that refer to rational and irrational beliefs influence the effect that those beliefs have on the FI. This finding was demonstrated when beliefs and their contents referred to either one's self or other people in a social context. Based upon the results of these two experiments, it may be prudent for REBT to modify its hypothesis that contents do not influence the effects that rational and irrational beliefs have on the FI. Specifically, it may wish to hypothesise that beliefs interact with contents to affect the FI.     

"Little rapes," specious claims, and moral hubris: a reply to Korn, Huelsman, Reed, and Aiello

Because they failed to include our informed consent, guided imagery scenarios, and debriefing, the relevance of Koren, Huelsman, Reed, and Aiello's (1992) data remains unknown. The design of their Study 1 did not test the greater objectivity of role taking over involved participation. The design of their Study 2 did not demonstrate the effects of demand characteristics. The older "personal acquaintances" were not at higher risk of rape as they claimed. Properly gathered data from the University of Connecticut's laboratory demonstrated that participants regarded the guided imagining of rape to be personally and scientifically beneficial, educating them about the crime and the experience of the rape victim. Prior research had demonstrated that exposure to rape stimuli in combination with debriefing had an educational effect on the decreased endorsement of rape myths. Previously published ethical principles for balancing the rights of scientists, subjects, and society explicate our ethical stance. Informed consent precludes the occurrence of wrongful harms. This poorly designed and poorly reasoned "ethical" critique was unfounded; yet, it might produce a chilling effect on both the use of guided imagery and freedom of inquiry into politically sensitive topics.     

Assertive community treatment for frequent users of psychiatric hospitals in a large city: A controlled study

Evaluated a large-city adaptation of the assertive community treatment (ACT) model (Stein & Test, 1980). Outcomes were examined after 1 year for 82 clients, averaging over 17 lifetime psychiatric hospitalizations, randomly assigned either to ACT or to a drop-in (DI) center. After 1 year, 76% of the ACT clients and only 7% of DI clients were involved in the respective programs. The ACT team averaged 2 home and community visits per week to each client. ACT clients averaged significantly fewer state hospital admissions and state hospital days than did DI clients. ACT clients reported greater satisfaction with program services, fewer contacts with the police, and less difficulty with practical problems associated with psychiatric readmission. More ACT clients were known to have stable community housing. Annual per-client treatment costs for ACT were estimated to be $1,500 less than for DI.     

Choice of extinction-signalling stimuli by rats

Rats in a two-lever situation were exposed to alternating periods of intermittent reinforcement and extinction. Extinction periods were either unsignalled or were signalled by a response-produced stimulus. The signal was sometimes a stimulus paired with food delivery in the reinforcement periods and sometimes a stimulus that occurred only in extinction periods. Both kinds of signal accelerated extinction relative to the unsignalled condition. When the signal was the stimulus paired with food in reinforcement periods, the rats tended to prefer the lever that gave that signal even though the signal accelerated extinction. There was no comparable effect for the stimulus that occurred only in extinction periods; when this signal was contingent on only one of the two levers, the rats either avoided it (Experiment 3) or were indifferent (Experiment 4). It is concluded that a stimulus can be a “secondary reinforcer” as measured by preference, even though it decreases resistance to extinction; the implications are discussed with reference to formal theories of choice behavior.     

THE EFFECT OF SPACED VS. MASSED PRESENTATION OF AGGRESSION ITEMS ON VERBAL AGGRESSIVE RESPONSES OF CHILDREN

A story completion test was constructed and administered to 99 ten-year-old boys. The main results were: (1) The average number of aggressive responses tends to be lower when the aggression items are presented in a 'spaced' manner than when they are 'massed'. (2) There is a spread effect from aggression items to neutral items. Aggression and neutral items presented in mixed order give a stronger effect. (3) A relatively consistent factor structure of aggression responses was shown in the test. Aggression towards peers and authority were independent of each other, and seem to be influenced differently by the manner of presentation of stimuli.     

Innovations in Assessing ADHD: Development, Psychometric Properties, and Factor Structure of the ADHD Symptoms Rating Scale (ADHD-SRS)

This research involved the development of a behavior rating scale designed to measure ADHD and the investigation of the scale's psychometric properties and factor structure. This scale, the ADHD Symptoms Rating Scale (ADHD-SRS), was developed for the assessment of ADHD in the school-age (K–12) population. Participants were 1006 children and adolescents (in grades K–12) who were rated by their parents and/or teachers. The results indicate that the ADHD-SRS possesses strong internal consistency reliability and test–retest reliability and moderate cross-informant reliability. The data also suggest that the ADHD-SRS has strong content validity. Convergent validity of this instrument was also high, as demonstrated by correlations with three previously validated behavior rating scales. Significant age and gender differences in ADHD symptoms were found with both the parent and teacher respondent populations. Finally, the factor analysis of the ADHD-SRS suggested a two factor oblique rotation as the best fit for both the parent and the teacher data. After a visual inspection of the items which loaded on each factor, Factor 1 was named Hyperactive-Impulsive and Factor 2 was named Inattention. These two factors, along with the items which loaded on each factor, appear to be remarkably similar to the two categories listed in the DSM-IV for ADHD. Directions for future research, as well as clinical implications and limitations of the research are discussed.     

Categorization of natural movements by pigeons: visual concept discrimination and biological motion

In three experiments, pigeons were exposed to a discriminated autoshaping procedure in which categories of moving stimuli, presented on videotape, were differentially associated with reinforcement. All stimuli depicted pigeons making defined responses. In Experiment 1, one category consisted of several different scenes of pecking and the other consisted of scenes of walking, flying, head movements, or standing still. Four of the 4 birds for which pecking scenes were positive stimuli discriminated successfully, whereas only 1 of the 4 for which pecking was the negative category did so. In the pecking-positive group, there were differences between the pecking rates in the presence of the four negative actions, and these differences were consistent across subjects. In Experiment 2, only the categories of walking and pecking were used; some but not all birds learned this discrimination, whichever category was positive, and these birds showed some transfer to new stimuli in which the same movements were represented only by a small number of point lights (Johansson's “biological motion” displays). In Experiment 3, discriminations between pecking and walking movement categories using point-light displays were trained. Four of the 8 birds discriminated successfully, but transfer to fully detailed displays could not be demonstrated. Pseudoconcept control groups, in which scenes from the same categories of motion were used in both the positive and negative stimulus sets, were used in Experiments 1 and 3. None of the 8 pigeons trained under these conditions showed discriminative responding. The results suggest that pigeons can respond differentially to moving stimuli on the basis of movement cues alone.     

Perception of object unity in chicks: A comparison with the human infant

Newly hatched chicks (Gallus gallus) were imprinted on a display consisting of two rod pieces that moved above and below a central occluder. On test trials, the chicks approached a complete rod in preference to two rod pieces. This finding, supported by those from control coditions, suggests that chicks, soon after hatching, perceive object unity. The results are compared with those from human infants.     

Cross-modality matching of brightness to loudness by 5-year-olds

The purpose was to determine whether 5-year-old children could match the brightness of a light to the loudness of a sound, and whether the resulting cross-modality function resembled the power function produced by adults. Each of five children adjusted the voltage on a 15D-W lamp to make the apparent brightness appear equal to the loudness of a 500-Hz tone, which the E set to eight different levels. The results resembled those of five adults who performed the same task.
