Intermodality relations in localization in blind and sighted people

Developmental data were gathered on the relative importance of vision, audition, and proprioception in determining spatial direction in a conflict situation. Age trends did not support the hypothesis that information from different modalities becomes better differentiated with age. In a follow-up study, blind children of different ages were tested under auditory-proprioceptive conflict conditions. No age changes were found. The possibility of a visual involvement in auditory and proprioceptive localization is discussed.     

Response bias in very first judgments of the reflectance of grays: Numerical versus linear estimates

Three hundred unsophisticated Os judged the lightness of a gray, reflectance 44%, against a white, reflectance 83%. Half gave a numerical estimate calling the white 100. The remainder marked a 100 mm line labeled 100 at one end and zero at the other. Both distributions of estimates were skewed with a mode around 60. The linear estimates tended to avoid the middle of the line (p<.01).The numerical estimates tended to end in zero or five (p<.001). The two distributions were not quite reliably different, but the medians of subgroups of 10 Os drawn from the two distributions were reliably different (p<.05).     

The effects of autobiographical elaboration on noun recall

Four experiments demonstrate that autobiographical elaboration is a rich and powerful encoding process. Autobiographical elaboration was induced by using a modified free-association procedure. Subjects were presented stimulus words and were instructed to think of a personal experience that the words reminded them of and to date the remembered experience on a 7-point temporal-category scale (i.e., minutes, hours, days, weeks, months, years, never). Unexpected free recall of the stimulus words showed a recency effect (Experiments 1, 3, and 4), autobiographical orienting produced better noun recall than either a semantic or a structural orienting task (Experiments 2 and 3), and the recency effect observed in Experiments 1, 3, and 4 appears to have been due to differences in autobiographical elaboration (Experiment 4).     

Role relevant sex typing and opportunity in agentic and communal domains1

The hypothesis associating psychological androgyny with greater personal adjustment has recently been contradicted in several studies in which masculine individuals, regardless of gender, generally appeared to be better adjusted than either androgynous or feminine persons. In the present research, five studies involving 363 subjects tested the hypothesis that such data may reflect a culture that values and differentially rewards agentic (masculine) characteristics and competencies in both men and women while taking communal (feminine) characteristics somewhat for granted. Subjects evaluating candidates for agentic roles preferred masculine candidates (regardless of gender). Masculine and androgynous persons were preferred for a communal role, while feminine persons were almost never chosen for either agentic or communal roles.     

Increasing purposeful activity of severely and profoundly mentally-handicapped adults

A time-series reversal design was used to evaluate the effect of a ‘room manager’ procedure on the level of purposeful activity of severely and profoundly mentally-handicapped people in a residential home. The room manager procedure consisted of systematic prompts to participate in recreational activity and social reinforcement contingent on engagement. Data were collected on group and individual client behaviour and two measures of staff performance were taken to assess whether the procedure was implemented consistently across subjects and in line with the experimental design. The results showed that, as well as a group of subjects who engaged at a higher level during the room manager condition, there were consistently ‘high-engaging’ and ‘low-engaging’ groups, reflecting in part the general level of ability of the subjects. However, data on the independent variables show that the the contingency of staff contact did not vary across conditions and it cannot therefore be assumed that these subjects would not respond to the intervention. Some limitations of the procedure as used are discussed, and areas where further work is needed are indicated.     

A SIMPLIFIED TIME-SERIES ANALYSIS FOR EVALUATING TREATMENT INTERVENTIONS

Time-series analysis procedures for analyzing behavioral data are receiving increasing support. However, several authorities strongly recommend using at least 50–100 points per experimental phase. A complex mathematical model must then be empirically developed using computer programs to extract serial dependency from the data before the effects of treatment interventions can be evaluated. The present discussion provides a simple method of evaluating intervention effects that can be used with as few as 8 points per experimental phase. The calculations are easy enough to do by hand.
