Visual selective attention with virtual barriers

Previous studies have shown that interference effects in the flanker task are reduced when physical barriers (e.g., hands) are placed around rather than below a target flanked by distractors. One explanation of this finding is the referential coding hypothesis, whereby the barriers serve as reference objects for allocating attention. In five experiments, the generality of the referential coding hypothesis was tested by investigating whether interference effects are modulated by the placement of virtual barriers (e.g., parentheses). Modulation of flanker interference was found only when target and distractors differed in size and the virtual barriers were beveled wood-grain objects. Under these conditions and those of previous studies, the author conjectures that an impression of depth was produced when the barriers were around the target, such that the target was perceived to be on a different depth plane than the distractors. Perception of depth in the stimulus display might have led to referential coding of the stimuli in three-dimensional (3-D) space, influencing the allocation of attention beyond the horizontal and vertical dimensions. This 3-D referential coding hypothesis is consistent with research on selective attention in 3-D space that shows flanker interference is reduced when target and distractors are separated in depth.     

‘It's a boy because he's painting a picture’: Age differences in children's conventional and unconventional gender schemas

Two studies investigated the development of children's gender knowledge using a procedure designed to tap into children's unconventional gender beliefs. Study 1 revealed a developmental progression with 34 3‐ to 4‐year‐old children providing more unconventional reasons than conventional reasons to explain the gender of a series of drawings. By contrast, 39 5‐ to 6‐year‐old and 42 7‐ to 8‐year‐old children provided more conventional than unconventional reasons. Study 2 found that a second sample of 42 3‐ to 4‐year‐old children mastered a close‐ended assessment of gender stereotyping, while they relied on unconventional and conventional reasoning equally when explaining the gender of a series of drawings displaying conventional cues only. This research supports the model that children's conventional gender schemas do not develop before their unconventional gender schemas.     

Coming to terms: Using technology to know identity

Recent advances in information and communication technologies have led some cultural theorists to hypothesize that Western society is undergoing a dramatic change in ways of knowing one’s self and identity. Cases in point are those people who identify as “trans” (i.e., cross-dressers, transsexuals, transgendered persons). In the first half of the twentieth century, trans persons had very limited contact, if any, with others like themselves. The argument of cultural theorists is that increasingly sophisticated information and communication technologies have encouraged the development of trans communities across North America. An analysis of the narratives in an oral history project involving Toronto’s trans community largely supports the assertions of project involving Toronto’s trans community largely supports the assertions of cultural theorists. The majority of respondents felt communication technologies played a central role in their developing sense of gender. Communication technologies generally provided a sense of connection with others, alleviated the isolation and loneliness, and provided hope by showing that a trans person’s life was possible. However, many respondents also reported critical misgivings about communication technologies and their influence on trans subjectivities.     

Inhibition of irrelevant category-response mappings

When switching tasks, performance tends to be worse for n - 2 repetitions than with n - 2 switches. This n - 2 repetition cost has been hypothesized to reflect task-set inhibition: specifically, inhibition of irrelevant category-response mappings involved in response selection. This hypothesis leads to divergent predictions for situations in which all tasks involve the same stimulus categories: An n - 2 repetition cost is predicted when response sets differ across tasks, but not when the response set stays the same. The authors tested these predictions by having subjects perform relative judgements with different reference points. In Experiment 1, the stimulus categories were the same across reference points, but the response set either differed or stayed the same (the multiple- and single-mapping conditions, respectively). An n - 2 repetition cost was found in the multiple-mapping condition but not in the single-mapping condition. Experiment 2 provided evidence against the possibility that these divergent effects reflected differences in memory load. These findings confirm predictions that link n - 2 repetition costs to inhibition of irrelevant category-response mappings.     

Personality and Religion a study among 8‐11 year olds

A sample of 166 year four, year five and year six pupils completed the Francis scale of attitude toward Christianity together with the short‐form Revised Junior Eysenck Personality Questionnaire. The data extend the findings of previous research by demonstrating that psychoticism is the dimension of personality fundamental to individual differences in religiosity among a sample of children as young as 9‐11 years of age.     

MacLaboratory Controller: A switch and A/D interface between Apple’s Macintosh and peripheral apparatus

Apple’s Macintosh microcomputer has advantages over other systems used for laboratory control and data acquisition, especially because of its graphic and user-friendly features. However, a major perceived limitation has been its closed architecture. We describe an interface using the RS 422 modem port that supports up to 64 input/output (I/O) functions including analog-to-digital 4–12 channel input. The Controller software supplies an easily edited authoring tool in which functional relationships, logical operators, timing (millisecond accuracy), and counting functions are established through simple mouse and menu commands. Data from I/O functions may be displayed or saved as tab-delimited files that can be opened by various Macintosh statistical and spreadsheet packages and that are transportable to some mainframe applications.     

Sequential search by groups with rank-dependent payoffs: An experimental study

In many sequential search situations, decisions are reached by groups. We examine behavior in such situations experimentally using an extension of the “secretary problem”. In our setup, group members (players) with non-aligned preferences inspect alternatives or “applicants” one at a time with no backward solicitation. A minimal information structure is assumed where players are only informed of the relative ranks of the alternatives as they inspect them sequentially. We present the equilibrium solution, and then use it as a benchmark for our analysis. We report the results from a controlled experiment showing that subjects over-searched relative to equilibrium. Decisions were affected by theoretically irrelevant observations including the relative rank of the previous alternative and the other player’s relative rank of the current alternative. For managers engaged in committee sequential search tasks, our findings highlight the importance of being aware to reach compromises early on, among other implications.     

Influential Factors in Artist's Lives and Themes in Their Artwork

ABSTRACT: The purpose of this study was to investigate the relations among influential factors in artists' lives, the process of creativity, and themes in the resulting artwork. Both qualitative and quantitative methods were used. In Phase I of the research, 6 contemporary artists identified themes, influences, feelings, thoughts, and representations about 5 pieces of their own art. They also completed a 50-item survey about influential factors. Two judges also were asked to identify themes, influences, feelings, thoughts, and representations in Phase 2 of the research. The judges relied on 30 slides depicting the work of the 6 artists. The same 50-item survey concerning influential factors was completed by each of the judges while examining the slides a 2nd time. Hypothesis 1, which predicted that artists would articulate the events, experiences, and memories that have influenced their lives, was supported. Hypothesis 2, which predicted that artists would be aware of the relations between influential factors in their lives and specific themes, images, expressions, and representations in their paintings, also was supported. Hypothesis 3, which predicted that potentially influential factors would be communicated in the themes, images, expressions, and representations in artists' paintings, and that objective viewers can identify them, was supported partially. The judges responded similarly to at least 2 of the 5 pieces of art for each participant. Hypothesis 4, which predicted that influential themes would be similar across all participants ' paintings, also was supported partially. One hundred percent agreement was found for the strongest influences (e.g., loss and culture) when the men and the women were evaluated separately.
