The “lag effect” in dichoptic viewing

Ten subjects were asked to report both of two different consonant-vowels (CVs) presented to the same foveal area, but in different eyes (“dichoptically”). Stimuli were presented at stimulus-onset asynchronies (SOAs) ranging from 0 to 150 msec in 25-msec steps. Correct identifications were significantly depressed for the eye receiving the leading stimulus at SOAs of 25 to 75 msec. Monoptic data from three subjects indicated no significant reductions in correct identification as a function of SOA. The dichoptic results can be understood in terms of current theories of visual backward masking and are similar to the “lag effect” observed with dichotic listening to speech stimuli. Similarity of results for the two modalities suggests a similar “two-process” explanation may underlie both phenomena.     

On the nature of the verbal memory deficit in Alzheimer''s disease

Verbal memory was investigated in patients with Alzheimer's disease (AD) with previously documented deficits in word production and comprehension. Procedures were employed to evaluate word recall and recognition within the context of both "multistore" and "levels of processing" models of memory. In addition, memory abilities were evaluated with respect to performance on measures of verbal fluency and language comprehension. As expected, the AD patients performed significantly worse than normal individuals on all tasks. However, in each experiment their pattern of recall across conditions was found to be qualitatively similar to that produced by normal subjects. It was argued that the memory impairment associated with Alzheimer's disease may be largely due to an inability to encode a sufficient number of stimulus features or attributes. Furthermore, this encoding deficit includes, but is not limited to, semantic attributes. Similarities between the performance of the AD patients and reported findings with Korsakoff patients and normal subjects with "weak" memory were discussed.     

The early resumption of employment by mothers: Implications for parent-infant interaction

Home observations of mother-father-infant interaction and mother-infant interaction were contrasted in middle-class families in which the mother was employed or a full-time caregiver. First-born infants and their parents were observed at 3 months. The results indicate that when mother, father, and infant were together parents in the single wage-earner families provided more tactile stimulation to their babies; fathers in single wage-earner families tended to interact more with their infants than did mothers, while in dual wage-earner families mothers tended to interact more than fathers; and fathers in single wage-earner families exceeded fathers in dual wage-earner families in interactions with their infants. By contrast, mothers in the two groups showed very little difference in their interactions with their babies. No significant differences were found for maternal behavior in the three-person observation, and a single behavior differentiated between the groups in the mother-baby observation, with homemaker mothers more often making visual contact with their babies. The implications of these findings are discussed, both with respect to further research, and with regards to the development of children of employed mothers.     

Parafoveal attention in congenitally deaf and hearing young adults

This reaction-time study compared the performance of 20 congenitally and profoundly deaf, and 20 hearing college students on a parafoveal stimulus detection task in which centrally presented prior cues varied in their informativeness about stimulus location. In one condition, subjects detected a parafoveally presented circle with no other information being present in the visual field. In another condition, spatially complex and task-irrelevant foveal information was present which the subjects were instructed to ignore. The results showed that although both deaf and hearing people utilized cues to direct attention to specific locations and had difficulty in ignoring foveal information, deaf people were more proficient in redirecting attention from one spatial location to another in the presence of irrelevant foveal information. These results suggest that differences exist in the development of attentional mechanisms in deaf and hearing people. Both groups showed an overall right visual-field advantage in stimulus detection which was attenuated when the irrelevant foveal information was present. These results suggest a left-hemisphere superiority for detection of parafoveally presented stimuli independent of cue informativeness for both groups.     

Atmospheres of the other: Building and feeling Stockholm's orthodox synagogue

In this article, I use the concept of atmosphere to analyse disparate sources related to the process of sacralisation of the orthodox synagogue Adass Jisroel in modern Stockholm. Using the synagogue as an entry point, I explore the affective landscapes related to its unofficially sacred places in firstly a Pietist orphanage and secondly a cinema, and how they shaped inner-communal relations. The material components of Adass Jisroel's sites elicited different emotions from different visiting bodies: its orthodox members aimed to create a space of religious continuity and communal integrity, reformed guests othered the members, while poorer orthodox Jews felt alienated. By analysing these multiple affective experiences linked to material changes of set architectural designs, I outline, for the first time, the orthodox minority's unstable position between fragility and stability in Sweden's capital from 1870 until the 1940s. On a greater scale, through this case study, I propose that the concept of atmosphere provides the field of emotional geography with conceptual muscle to both excavate silenced minority voices, and explore the role of the built environment in eliciting emotions that shape, cement, contest and transform the inner-communal hierarchal landscape that unofficially sacred places are irrevocably situated in.     

Church or Factory: Radical Inclusivity and Vanguard Practice in 1960s New York

Art historians have often discussed Andy Warhol's Factory as a unique creative space in 1960s Manhattan. Similarly, scholars of dance and performance have provided valuable insight into the vanguard activities associated with the Judson Dance Theater located near Union Square. Few studies take time to compare these two places and consider their relationships to one another. This article looks at Warhol's Silver Factory and the performances that took place at Judson Memorial Church more or less simultaneously with a goal of identifying overlapping actors and establishing shared concerns and a sense of radical inclusivity that existed at both sites.     

A five-dimensional model of individual differences in social exchange styles

An evolutionary psychology framework was used to develop a five-factor model of individual differences in the domain of social exchange that built on a prior two-factor model (Leybman, Zuroff, Fournier, Kelly, & Martin, 2011). Two studies examined the factor structure of the revised Social Exchange Styles Questionnaire (SESQ-II), the reliability and validity of its five scales, and the relationship between social exchange styles (SESs) and social support. Principal components and principal factor analyses of the SESQ-II in 226 undergraduates found five social exchange dimensions: Tracking, Fairness, Individualism, Benefit-Seeking, and Overinvestment. These scales showed good internal consistency and retest reliability. Multiple regression analyses demonstrated that SESs, while distinct from other personality variables, had expected relationships with several variables and predicted social support patterns.     

The watershed years of 1958-1962 in the Harvard Pigeon Lab

During the years 1958-1962, the final years of support by the National Science Foundation for B. F. Skinner's Pigeon Lab in Memorial Hall at Harvard University, 20 or so pigeon experiments (plus some with other organisms) ran concurrently 7 days a week. The research style emphasized experimental analyses, exploratory procedures, and the parametric exploration of variables. This reminiscence describes some features of the laboratory, the context within which it operated, and the activities of some of those who participated in it.     

ALTRUISM AND THE ADMINISTRATION OF THE UNIVERSE: KIRTLEY FLETCHER MATHER ON SCIENCE AND VALUES

Abstract. Few American scientists have devoted as much attention to religion and science as Harvard geologist Kirtley Fletcher Mather (1888–1978). Responding to antievolutionism during the 1920s, he taught Sunday School classes, assisted in defending John Scopes, and wrote Science in Search of God (1928). Over the next 40 years, Mather explored the place of humanity in the universe and the presence of values in light of what he often called “the administration of the universe,” a term and concept he borrowed from his former teacher, geologist Thomas Chrowder Chamberlin. Human values, including cooperation and altruism, had emerged in such a context: “the administrative directive toward orderly organization of increasingly complex systems transcends the urge for survival.” He was also active in the early years of the Institute on Religion in an Age of Science, an organization created by his good friends Ralph Wendell Burhoe and Harlow Shapley.
