The effects of verbal feedback and listener type on the speech of preschool children

The present study simultaneously assessed the relative contributions of feedback indicative of comprehension and the apparent age of the listener, either an adult or a doll which resembled a toddler, in a 2 (listeners) × 2 (types of feedback, C = comprehension, NC = noncomprehension) design. Two groups of children, a 3-year-old (N = 13, 7 boys, 6 girls) and a 5-year-old group (N = 12, 6 boys, 6 girls) were asked to tell stories to both the adult and doll in both C and NC conditions. The doll was constructed with an internal speaker such that it could actually carry on a conversation with the children. The conversations were taped, transcribed, and scored for mean length of utterance (MLU), transitional utterance length to each C and NC signal, and the proportion of child questions, exact self-repetitions, repetition and reductions, and rephrases/elaborations. The data analysis revealed that all children appropriately modified the length of their utterances (MLU) in the doll condition but not in the adult condition, indicating that they were sensitive to both the feedback and the nature of their listeners. Older children were more likely than younger children, and girls more likely than boys to adjust the length of their utterances appropriately to each type of feedback, slightly increasing the length of the subsequent utterance to a C signal and decreasing the length to an NC signal. The younger children were also more likely to respond with a simple repetition to NC cues from the adult.     

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).     

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)     

Size judgment: The presence of a standard increases the exponent of the power law

Ss judged the size of circles by the methods of magnitude estimation and magnitude production, with or without a standard figure present. The presence of the standard raised the exponent of the power law. The effect was largely independent of the position of the standard in the range of stimuli. It is argued that the standard’s effect was not mediated by a difference in apparent size between perceived and remembered standards, a change in Ss’ response strategies, a decrease in sequential dependencies, or other previously identified bias effects.
