Effects of behavioral training on the functioning of a profoundly retarded microcephalic teenager with cerebral palsy and without language or verbal comprehension: A case study

In previous investigations (Jacobson, Berger, Bergman, Millham and Greeson, 1971; Jacobson and Greeson, 1972), it was reported that as a result of the use of a behavior modification program, preschool children from poverty backgrounds demonstrated rapid conceptual acquisition. In addition, the Ss increased from the dull-normal to the normal range of intellectual functioning within approximately 20 hr of program participation. Since the increases in IQ found were most pronounced for children of lowest IQ (IQs = 46–83), the investigators hypothesized that the program would prove to be useful with Ss of greater cognitive and behavioral deficits than the initial population investigated.The present study reports the use of a variant of the conceptual acquisition program with an institutionalized, profoundly retarded microcephalic teenager with chronic brain syndrome and cerebral palsy. Prior to the study the boy demonstrated neither language nor an ability to comprehend and follow verbal directions.     

Sex differences in visuospatial ability: Do performance factors play such an important role?

This study was designed to analyze some performance factors as a possible source of sex-related bias in psychometric tests of visuospatial aptitude. Goldstein, Haldane, and Mitchell (1990) explored the effect of two response styles—slowness of performance and reluctance to guess—by using a 3-D mental rotation test (the task showing the largest cognitive sex difference) and found that time limits and raw scores contributed substantially to the male advantage. We applied two tests in thespeed-power continuum to a representative sample of 621 males and 821 females in their last year of high school in a 2 × 2 (gender × time) full factorial design. Reluctance to guess was similar for males and females. Males obtained more correct responses on both tests, and for both time conditions, than did females. These results are not only statistically significant but also are of substantial practical consequence.     

Bilingual computerized speech-recognition screening for clinical depression: Evaluating a cellular telephone prototype

This exploratory field study evaluated a bilingual computerized speech-recognition cellular telephone prototype of the Center for Epidemiological Studies—Depression scale (CES-D). Thirty Spanish and 22 English speakers completed both computer-telephone and face-to-face CES-D methods and an oral depression checklist in counterbalanced order. Both language groups reported high positive ratings for the computer-telephone method, with the English sample preferring the computer-telephone over the face-to-face method. In both samples, the computer-telephone method yielded high internal consistency estimates, strong alternate form reliabilities, and similar high correlations to the depression checklist. Both groups reported significantly elevated scores with the computer-telephone method, but total score variances for both methods did not differ. Computer-telephone limitations included occasional misrecognitions and template training constraints.     

The Cultural Factor in Lay Perception of Jealousy as a Motive for Wife Battery1

Cultural psychology is concerned with the comparative study of the way culture and psyche shape each other: This process is particularly well illustrated in the social construction of some feelings. Although sexual jealousy seems to be universal, people differ in the intensity of their reactions and in the type of stimuli perceived as threatening. Replicating previous research in Britain by Delgado and Bond (1993), a questionnaire research survey was conducted in Spain to determine if lay perception considers jealousy a justification for wife battery. The comparison of results shows striking differences: The harmdoer was seen as more guilty in Britain and the victim was seen as more guilty in Spain. Results demonstrate cultural differences in the perception of jealousy; when jealousy is a motive for assault, there are also cultural differences in judgments of responsibility. Emotions function differently in different cultures regarding perceived causes and justification for conduct.     

Future Thinking in Disadvantaged Situations: The Role of Outcome Delays and Competitive Issues in Negotiation

Extant literature suggests that delaying the outcomes of negotiations can have salutary effects on the joint outcomes of participants. However, this literature has not examined the impact that outcome delays have on the success of individual negotiators. We argue that in situations where a player's preference on an issue involves a lack of legitimacy, an outcome delay may advantage the presentation of that issue. In addition, we suggest that this effect is more likely to be present in situations where competition is high, specifically, where the parties have few opportunities for cooperation. An experimental dyadic negotiation exercise involving 306 undergraduate participants was conducted to test these hypotheses. Results suggest that the introduction of an outcome delay helps to reduce the negative effects of a legitimacy disadvantage in the absence of alternate opportunities for collaboration.     

Acquisition of mental state language in Spanish children: a longitudinal study of the relationship between the production of mental verbs and linguistic development

The development of language indicating the emergence of thinking about the thoughts of self and others has been scarcely studied in Spanish-speaking children. For this reason, we studied the development of mental state language and various indicators of language development in 25 Spanish-speaking children assessed at 3, 3 1/2, 4, 4 1/2, and 5 years of age. We coded and categorized the 40,250 utterances children produced during the five time points, 1202 (3.01%) of which had mental terms. In this sample, mental state language in Spanish children developed with a similar timeline and patterns as described in English-speaking children. However, several findings were novel for studies of mental state language. The general indexes of syntactic development did not correlate with the production of mental terms. The Index of Lexical Diversity was associated with the frequency of references to verbs of desire. The results of regression analyses suggest that not only the development of subordinate sentences with complement is associated with genuine mental references to desires and beliefs, but the development of lexical skills as well.     

Enhanced inhibitory avoidance learning prevents the long-term memory-impairing effects of cycloheximide,a protein synthesis inhibitor

Interference with activity of numerous cerebral structures produces memory deficiencies; in many instances, however, when animals are over-trained such interference becomes innocuous. Systemic administration of protein synthesis inhibitors impairs long-term retention; this effect has been interpreted to mean that protein synthesis is required for memory consolidation, though little is known about the effect of protein synthesis inhibitors on memory of enhanced learning in the rat. To further analyze the protective effect of enhanced learning against amnesic treatments, groups of Wistar rats were trained in a one-trial step-through inhibitory avoidance task, using different intensities of foot-shock during training. Cycloheximide (CXM; 2.8 mg/kg), an inhibitor of protein synthesis, was injected either 30 min before training or immediately after training. Twenty-four hours after training retention latencies were recorded. Our data showed that both pre- and post-training administration of CXM produced amnesia in those groups that had been trained with relatively low foot-shock intensities, but no impairment in retention was observed when relatively high intensities of foot-shock were administered. These and similar results lead us to conclude that protein synthesis inhibitors may interfere with memory consolidation, but their effect disappears when animals are submitted to an enhanced learning experience, calling into question the idea that protein synthesis is required for memory consolidation.     

Retrospective reports of dream characteristics and preferences for organic vs. junk foods

The authors investigated correlations between retrospective dream characteristics, food preferences, and eating attitudes. Graduate students (7 men, 42 women) at Santa Clara University were administered the MEGA food scale and the KJP Dream Inventory. High intake of organic food was positively correlated with reports of multiple dream factors. Conversely, high scores on preferences for fast food, potato chips, and carbohydrates were negatively correlated with several factors. Findings are discussed in terms of the hypothesis that certain foods may influence dreaming.     

Differential effects of instructions and consequences on human conditional discrimination performance

Two studies evaluated the differential behavioral effects of instructions and feedback in matching-to-sample procedures. In Experiment 1, 20 college students received true or false instructions and trial-by-trial or delayed feedback in three phases. In a fourth, final phase the instructions remained the same, but feedback changed from trial-by-trial to delayed, or from delayed to trial-by-trial. In Experiment 2, half of another 20 participants received true instructions during three phases, followed by false instruction in a fourth phase; the other half of the participants received false instructions during three phases, followed by true instructions in the fourth phase. Feedback sequences were as in Experiment 1. The results of both experiments revealed historical effects of instructions and feedback. Most participants demonstrated strong instructional control, overriding the control by contingencies. These results suggest that the present procedure offers optimal possibilities to make the differential effects of instructions and feedback on human behavior clearly identifiable when conditional discrimination tasks are used.
