On the role of outline shape and word-specific visual pattern in the identification of function words: None

A common assumption in the reading literature is that function words are often identified wholly or in part on the basis of outline shape and/or word-specific visual pattern. This assumption was examined in three perceptual identification experiments, a speeded oral reading experiment, and in a lexical decision task where the visual pattern of function words and control items (content words, non-words and control strings) was systematically distorted by cAsE alTeRnA-tIoN. In all five experiments distortion failed to impair performance more on functors than on various control items. This result is argued to be inconsistent with the view that outline shape and word-specific visual pattern typically play a role in the identification of isolated function words.

Shape distortion impaired function words less than controls in perceptual identification, but impaired function and content words equally in speeded naming and lexical decision. These contrasting effects of shape distortion are discussed in terms of a distinction between the uptake of information (lexical access) and phenomenal perception.     

An evidential support accumulation model of subjective probability

A model of cue-based probability judgment is developed within the framework of support theory. Cue diagnosticity is evaluated from experience as represented by error-free frequency counts. When presented with a pattern of cues, the diagnostic implications of each cue are assessed independently and then summed to arrive at an assessment of the support for a hypothesis, with greater weight placed on present than on absent cues. The model can also accommodate adjustment of support in light of the baserate or prior probability of a hypothesis. Support for alternatives packed together in a "residual" hypothesis is discounted; fewer cues are consulted in assessing support for alternatives as support for the focal hypothesis increases. Results of fitting this and several alternative models to data from four new multiple-cue probability learning experiments are reported.     

Doubting one’s doubt: A formula for confidence?

People feel, think, and act differently when doubt rather than confidence is accessible. A traditional perspective on the accessibility of doubt holds that multiple sources of doubt activation should lead to increased levels of uncertainty. In contrast, we find that under some conditions two sequential sources of doubt activation result in decreased levels of uncertainty. We suggest that this follows from a meta-cognitive process in which people come to “doubt their doubt.” In Study 1, individuals with chronically accessible uncertainty who were further exposed to an uncertainty manipulation paradoxically reported reduced uncertainty. In Study 2, participants were first primed with doubt or certainty and then exposed to a manipulation associated with either confidence (i.e., head nodding) or doubt (head shaking). Supporting the idea that people can either trust or doubt their own doubts, head nodding (vs. shaking) accentuated (vs. attenuated) the impact of the initial doubt vs. certainty manipulation. These findings advance the literature on meta-cognition, self-doubt, and embodiment, and may have clinical applications.     

A validation of a computerised task of risk-taking and moral decision-making and its association with sensation-seeking,impulsivity and sociomoral reasoning

The aim of this study was to investigate the reliability and validity of the computer based application of the Secret Agent (SA) task of risk-taking and moral decision-making. The participants were 100 male patients in a maximum security hospital (50 with severe mental illness and 50 with personality disorder) and 50 community based healthy controls. All participants completed the SA task, the Iowa Gambling Task (IGT), and measures of IQ, antisocial personality traits, sensation-seeking, impulsivity and sociomoral reasoning. The SA risk-taking and moral decision-making scales had satisfactory levels of reliability (Cronbach’s alpha). Risk-taking correlated significantly with sensation-seeking across all three participant groups. In contrast, risk-taking only correlated with impulsivity among the severe mental illness group. Moral decision-making correlated with sociomoral reasoning among the personality disorder group. No correlation was found between the SA scores and the IGT score and the IGT did not correlate with sensation-seeking or impulsivity. IQ and antisocial personality traits did not correlate with the SA or IGT scales. The study highlights the importance of context, the nature of the risk-taking task, and ‘problem framing’ of the instructions in their relationship with individual differences.     

Editorial: Three Perspectives of Employment Discrimination 50 Years After the Civil Rights Act—A Promise Fulfilled?

Purpose

In recognition of the 50th anniversary of the Civil Rights Act of 1964, this paper reviews contradictory perspectives of the status of employment discrimination.

Design/Methodology/Approach

Arguments are derived from psychology, management, law, and political science to contrast perspectives that civil rights legislation has (a) done its job, (b) gone too far, and (c) not gone far enough.

Findings

We determine that disagreement is inevitable and that no unified conclusion can be drawn. Recognition of the viewpoints embedded in opposing perspectives, however, offers direction for the future of organizational science and practice.

Implications

Consideration of these disparate views of civil rights legislation enables thoughtful reflection on the past, present, and future of civil rights legislation.

Originality/Value

This paper offers a variety of lenses through which to consider employment discrimination in the organizational sciences and underscores the value of the papers collected in the special issue.     

Gender Differences in the Relationship Between Academic Self-Concept and Self-Reported Depressed Mood in School Children

In light of literature highlighting gender differences related to academic self-concept and depressed mood, this study explored the contributions of academic self-concept in individual subject areas to self-reported depressed mood in 86 elementary-age boys and girls from a province in central Canada. Results indicated that academic self-concept explained 68% and 62% of the variance in self-reported depressed mood for boys and girls, respectively. Separate analyses conducted for boys and girls indicated disparate predictive models that cohered with gender stereotypic self-perceptions: math for boys and reading for girls. Interestingly, physical education emerged as a significant contributor for boys and girls. Results are discussed in terms of the importance of addressing the relationship between children’s social-emotional self-perceptions and academic self-concept within domain-specific lenses.     

The malleability of age-related positive gaze preferences: training to change gaze and mood

Older adults show positive gaze preferences, but to what extent are these preferences malleable? Examining the plasticity of age-related gaze preferences may provide a window into their origins. We therefore designed an attentional training procedure to assess the degree to which we could shift gaze and gaze-related mood in both younger and older adults. Participants completed either a positive or negative dot-probe training. Before and after the attentional training, we obtained measures of fixations to negatively valenced images along with concurrent mood ratings. We found differential malleability of gaze and mood by age: for young adults, negative training resulted in fewer posttraining fixations to the most negative areas of the images, whereas positive training appeared more successful in changing older adults' fixation patterns. Young adults did not differ in their moods as a function of training, whereas older adults in the train negative group had the worst moods after training. Implications for the etiology of age-related positive gaze preferences are considered.     

Basic processes in reading: the effect of interletter spacing

Reading is acutely sensitive to the amount of space between letters within a string. In the present investigation, we explore the impairment caused by increasing interletter spacing when reading single words and nonwords aloud. Specifically, 2 hypotheses are tested: (a) whether increasing interletter spacing induces serial processing while reading aloud and (b) whether this serial processing results from an increased reliance on a serial sublexical mechanism similar to that implemented in dual route models of reading. Implications of the present results for understanding basic processes in reading are discussed with particular reference to different types of serial processing in reading aloud and the role of attention in reading.     

Twice upon a time: multiple concurrent temporal recalibrations of audiovisual speech

Audiovisual timing perception can recalibrate following prolonged exposure to asynchronous auditory and visual inputs. It has been suggested that this might contribute to achieving perceptual synchrony for auditory and visual signals despite differences in physical and neural signal times for sight and sound. However, given that people can be concurrently exposed to multiple audiovisual stimuli with variable neural signal times, a mechanism that recalibrates all audiovisual timing percepts to a single timing relationship could be dysfunctional. In the experiments reported here, we showed that audiovisual temporal recalibration can be specific for particular audiovisual pairings. Participants were shown alternating movies of male and female actors containing positive and negative temporal asynchronies between the auditory and visual streams. We found that audiovisual synchrony estimates for each actor were shifted toward the preceding audiovisual timing relationship for that actor and that such temporal recalibrations occurred in positive and negative directions concurrently. Our results show that humans can form multiple concurrent estimates of appropriate timing for audiovisual synchrony.
