Marital satisfaction,job satisfaction,and task distribution in the homemaker job

Several facets of the homemaker job were analyzed in terms of the dynamic relationship between husband and wife. Seventy-one husband and wife pairs completed a questionnaire which assessed satisfaction with the homemaker job, marital satisfaction, distribution of responsibility for homemaker tasks between husband and wife, and other variables. Wives' satisfaction with the homemaker job was found related to the degree to which husbands assumed responsibility for homemaker tasks and to the husbands' attitudes toward women in general. Wives' marital satisfaction was found related to the interaction of wives' employment status (job holder or full-time homemaker) and satisfaction with the homemaker job. Directions for future research in this area were suggested.     

Crowding: Effects of Group Size,Room Size,or Density?

The separate effects of group size, room size, and density (space per person) were investigated for subjects responding interactively or coactively to perceptual and cognitive tasks. The major findings are that crowding has greater effects on "feelings" and "interpersonal perceptions" than on task performance. Where crowding did have effects, they appeared to be mediated more by group size and, to some degree, room size than by density, especially for males. Female subjects appeared somewhat more density oriented than male subjects.     

Periodicity pitch perception and its upper frequency limit in cats

We have established a procedure for behavioral assessment of periodicity pitch perception in the cat. This procedure requires the training of cats to make a differential response to two different pure tones, and then testing for the transfer of learning when complex stimuli known to produce periodicity pitch sensations in humans are substituted for the pure tones. Complex stimuli consisted of three to five harmonically related frequencies of the same amplitude and phase. Eight cats were the subjects of these experiments. Two of them were controls. It is demonstrated here that cats do perceive periodicity pitch. We also used this procedure to measure the upper frequency limit of periodicity pitch perception for two cats. The frequencies tested were 100, 200, 300, 400, 600, 800, 900, and 1,200 Hz. The data indicate that the upper frequency limit of periodicity pitch perception in the cat is on the order of 600 to 800 Hz. There is a trend of decreasing prominence of the perception of periodicity pitch as the component frequencies are increased. These results are parallel to the human psychophysical data.
