Change detection and off-frequency listening: A reply to Leshowitz and Wightman

Leshowitz and Wightman’s (1972) account of the fact that recognition of increments and decrements in intensity improves with signal duration relative to detection of increments and decrements is found wanting. Not only does their interpretation fail to explain the occurrence of the effect in several different stimulus situations, but it is inconsistent with the results of detection experiments in which either signal duration or the signal polarity is uncertain.     

Recent developments in family behavioral marital therapy

This paper reviews recent developments in the area of behavioral marital therapy (BMT). New information is summarized regarding the long-term efficacy of BMT and the identification of predictors of positive response to treatment and to relapse. Finally, new applications of BMT techniques are reviewed (e.g., spouse-involved therapies as the sole treatment for presenting problems in which marital distress is not the primary focus such as anxiety and affective disorders).     

Menarche: prior knowledge and experience

The purpose of this study was to determine the details of first menstruation and the differences between those who had knowledge of menstruation prior to menarche and those who did not. Information from 305 young women in India was collected regarding menarcheal bleeding pattern, disturbances in normal menstruation, and menarcheal age. Those who had knowledge prior to menarche considered it to be a normal physiological function, while those who did not were "appalled" and "horrified." Those having prior knowledge had a high rate of regularity, lower rate of dysmenorrhea, and earlier onset of menarche. The subjects were unanimous in their desire for more information to be provided prior to menarche.     

DIFFERENCES BETWEEN MOTHERS AND FATHERS IN PREDICTION OF SON'S PERFORMANCE IN EASY THROUGH DIFFICULT EXAMS*

Twenty-four Indian couples predicted in confidentiality to the school principal, the performance, in very easy, ok, and very difficult exams, of several 12-year-old boys, presented as their only son. As hypothesized, pattern in the Motivation X Ability effect depended upon the experience of subjects with the task and the difficulty of the exams. Prediction by mothers conformed to the patterns of parallelism and linear fan; those by fathers conformed to the patterns of parallelism and convergence. The findings of the present research and those of past research lead to the conclusion that the egalitarian (i.e., pattern of parallelism), elitist (i.e., pattern of linear fan), and Horatio Alger (i.e., pattern of convergence) beliefs are present in Indian, as well as in North-American adults, but that Indians manifest the elitist and Horatio Alger beliefs very selectively. The implications of these results for cross-cultural research on cognitive processes and for the understanding of differences between mothers and fathers in the cognition of their son are discussed.     

Stimulus-response compatibility in the programming of speech

Subjects chose between sequences of one syllable (e.g.,/gi/vs./bi/), two syllables (e.g.,/gibi/ vs./gubu/), and three syllables (e.g.,/gibidi/ vs. gubudu/), when/i/sequences were signaled by high-pitched tones and/u] sequences were signaled by low-pitched tones (high compatibility), or the reverse (low compatibility). Choice times were additively affected by sequence length and compatibility. A second experiment showed attenuated compatibility effects for sequences with different vowels in the first and second syllables. These results replicate previously reported results for choices between finger sequences, which suggests that the same programming methods are used in both output domains. Evidently, choices between response sequences can be achieved by selecting a distinguishing parameter and assigning it in a serial fashion to partially prepared motor subprograms.     

Memory deficits before and after temporal lobectomy: Effect of laterality and age of onset

Laterality and age of onset effects on semantic and figural memory were evaluated in 30 right-handed, left speech dominant (amobarbital test) patients with epilepsy before and after temporal lobectomy. There were no effects of focus on WAIS-R IQ scores. Early onset (less than or equal to 5 years) was associated with lower IQ and memory (WMS). Left Temporal (LT) patients showed worse semantic than figural memory preoperatively. Unexpectedly, early onset LT had marked postoperative decline of figural memory, whereas late onset LT patients showed the previously reported worsening of semantic memory. Right Temporal (RT) lobectomy patients, in contrast, improved in both semantic and figural memory regardless of age of onset. A "crowding effect" was suggested by the decline in figural memory following surgery in the early onset LT patients who remained stable or improved in semantic memory. Results indicate the need to incorporate age of onset of seizures into laterality models of memory function following unilateral temporal-hippocampal resection.     

Internal standards revisited: Effects of social comparisons and expectancies on judgments of fairness and satisfaction

Two studies examined the effect of two comparison processes on perceptions of fairness and satisfaction. Rewards relative to others (social comparison) and relative to expectancies (expectancy comparison) were orthogonally varied while absolute level of reward was held constant. Both studies showed, contrary to previous theory, that only social comparisons are related to perceived fairness, yet both comparisons are significantly related to satisfaction in an additive manner. Social comparisons explained more variation in satisfaction and dominated responses to more specific measures of affect. Partial support for specific predictions derived from equity theory and expectancy theory are reported. The overall results are interpreted as demonstrating the importance of the salience of frames of reference in reward evaluation.Estabilished practices create expectations, and since men have traditionally received greater rewards than women for the same services, they expect disproportionate rewards and tend to be disappointed if they do not get them. But these expectations have nothing to do with investments, and neither are they rooted in a conception of justice. (Blau, 1964, p. 195)
