The role of facial colour and luminance in visual and audiovisual speech perception

We conducted four experiments to investigate the role of colour and luminance information in visual and audiovisual speech perception. In experiments 1a (stimuli presented in quiet conditions) and 1b (stimuli presented in auditory noise), face display types comprised naturalistic colour (NC), grey-scale (GS), and luminance inverted (LI) faces. In experiments 2a (quiet) and 2b (noise), face display types comprised NC, colour inverted (CI), LI, and colour and luminance inverted (CLI) faces. Six syllables and twenty-two words were used to produce auditory and visual speech stimuli. Auditory and visual signals were combined to produce congruent and incongruent audiovisual speech stimuli. Experiments 1a and 1b showed that perception of visual speech, and its influence on identifying the auditory components of congruent and incongruent audiovisual speech, was less for LI than for either NC or GS faces, which produced identical results. Experiments 2a and 2b showed that perception of visual speech, and influences on perception of incongruent auditory speech, was less for LI and CLI faces than for NC and CI faces (which produced identical patterns of performance). Our findings for NC and CI faces suggest that colour is not critical for perception of visual and audiovisual speech. The effect of luminance inversion on performance accuracy was relatively small (5%), which suggests that the luminance information preserved in LI faces is important for the processing of visual and audiovisual speech.     

Neglected questions in job design: How people design jobs,task-job predictability,and influence of training

Three questions important to job design interventions but neglected in research were explored. First, how do people design jobs? Internal processes (e.g., growth needs) from psychological (or job enrichment) models of job design were not apparent. Instead, groupings of tasks into jobs suggested simple cognitive categorization based on task similarity, reflecting an engineering (or work simplification) orientation. Second, can job design be predicted from task design? Separate measures for job and task designs were unrelated, indicating that the whole is not predictable from the parts in job design, Third, can job design principles be trained? Subjects easily learned and applied different job design approaches.     

Use of situational judgment tests to predict job performance: a clarification of the literature

Although situational judgment tests have a long history in the psychological assessment literature and continue to be frequently used in employment contexts, there has been virtually no summarization of this literature. The purpose of this article is to review the history of such tests and present the results of a meta-analysis on criterion-related and construct validity. On the basis of 102 coefficients and 10,640 people, situational judgment tests showed useful levels of validity (rho = .34) that were generalizable. A review of 79 correlations between situational judgment tests and general cognitive ability involving 16,984 people indicated that situational judgment tests typically evidence relationships with cognitive ability (rho = .46). On the basis of the literature review and meta-analytic findings, implications for the continued use of situational judgment tests are discussed, particularly in terms of recent investigations into tacit knowledge.     

Authoritarian dynamics and unethical decision making: high social dominance orientation leaders and high right-wing authoritarianism followers

When dilemmas require trade-offs between profits and ethics, do leaders high in social dominance orientation (SDO) and followers high in right-wing authoritarianism (RWA) make decisions that are more unethical than those made by others? This issue was explored in 4 studies with female participants performing managerial role-playing tasks. First, dyads comprising a person who was either low or high in SDO and a person who was either low or high in RWA negotiated for a leadership position. People high in SDO were more likely to obtain leader positions than to obtain follower positions. No other effects were significant. Second, leaders high in SDO partnered with an agreeable (confederate) follower made decisions that were more unethical than those of leaders low in SDO. Third, followers high in RWA were more acquiescent to and supportive of an unethical (confederate) leader than were followers low in RWA. Fourth, high SDO leader-high RWA follower dyads made decisions that were more unethical than those made in role-reversed dyads because leaders had more influence. Implications of these results for conceptualizing SDO, RWA, and authoritarian dynamics are discussed.     

Innovative Assessment of Childhood Trauma and Its Link to HIV and Substance Abuse in Post-Incarcerated Women

Women who are incarcerated often report unresolved early life traumas, which research has linked to subsequent HIV and substance abuse risks. This article presents an arts-based counseling technique used with women re-entering society after incarceration. Women were assessed for childhood trauma (i.e. sexual, emotional, and/or physical abuse) in relation to age of onset and frequency of events using an interactive pictorial assessment technique, Healing Me Timeline activity. The technique allowed women to use color-coded graphs in identifying points along a timeline during which traumatic events occurred and to process insights to foster healthy coping strategies. The timeline activity was an innovative and gender-appropriate method for uncovering the nature and extent of women’s trauma and counseling needs. Facilitators used the counseling tool to assist women in processing personal insights and to make referrals to mental health counseling, medical services, and substance use programs.     

The effects of voluntary movements on auditory-haptic and haptic-haptic temporal order judgments

In two experiments we investigated the effects of voluntary movements on temporal haptic perception. Measures of sensitivity (JND) and temporal alignment (PSS) were obtained from temporal order judgments made on intermodal auditory-haptic (Experiment 1) or intramodal haptic (Experiment 2) stimulus pairs under three movement conditions. In the baseline, static condition, the arm of the participants remained stationary. In the passive condition, the arm was displaced by a servo-controlled motorized device. In the active condition, the participants moved voluntarily. The auditory stimulus was a short, 500Hz tone presented over headphones and the haptic stimulus was a brief suprathreshold force pulse applied to the tip of the index finger orthogonally to the finger movement. Active movement did not significantly affect discrimination sensitivity on the auditory-haptic stimulus pairs, whereas it significantly improved sensitivity in the case of the haptic stimulus pair, demonstrating a key role for motor command information in temporal sensitivity in the haptic system. Points of subjective simultaneity were by-and-large coincident with physical simultaneity, with one striking exception in the passive condition with the auditory-haptic stimulus pair. In the latter case, the haptic stimulus had to be presented 45ms before the auditory stimulus in order to obtain subjective simultaneity. A model is proposed to explain the discrimination performance.     

Transition to the Clinical Doctorate: Attitudes of the Genetic Counseling Training Program Directors in North America

In North America, genetic counseling is an allied health profession where entry level practitioners currently must hold a master’s degree earned from a graduate program accredited by the American Board of Genetic Counseling. This is one of many health care professions that could transition to an entry level clinical doctorate degree. This study explored the attitudes of genetic counseling training program directors toward such a transition. Thirty-one North American program directors were invited to complete an online survey and a follow-up telephone interview. Twenty-one program directors completed the survey and ten directors also completed a follow up phone interview. There was disagreement among the respondents on the issue of transitioning to a clinical doctorate degree (nine in favor, six against and six undecided). Respondents disagreed about whether the transition would lead to higher salaries (six yes, eight no, and seven unsure) or increased professional recognition (eight yes, eight no, and four unsure). Approximately half (n = 10) of directors were not sure if the transition to a clinical doctorate would help or hurt minority recruitment; six thought it would help and four thought it would hurt. However, the majority (n = 13) thought a clinical doctorate would help genetic counselors to obtain faculty positions. If the field transitions to a clinical doctorate, 11 of the directors thought their program would convert, seven were unsure and one thought their program would shut down. Themes identified in interview data included 1) implications for the profession 2) institution-specific considerations and 3) perception of the unknown. Opinions are quite varied at this time regarding the possible transition to the clinical doctorate among genetic counseling training program directors.     

Movement and mirror neurons: a challenging and choice conversation

This paper raises fundamental questions about the claims of art historian David Freedberg and neuroscientist Vittorio Gallese in their article "Motion, Emotion and Empathy in Esthetic Experience." It does so from several perspectives, all of them rooted in the dynamic realities of movement. It shows on the basis of neuroscientific research how connectivity and pruning are of unmistakable import in the interneuronal dynamic patternings in the human brain from birth onward. In effect, it shows that mirror neurons are contingent on morphology and corporeal-kinetic tactile-kinesthetic experience. Accordingly, it poses and answers the overlooked but seminally important question of how mirror neurons come to be. The original neuromuscular research of Parma neuroscientists and the findings of Marc Jeannerod concerning kinesthesia support the answer that the "underpinnings" of visual art appreciation are themselves underpinned. An abbreviated phenomenological analysis of movement and its implications regarding the fact that the making of all art is quintessentially contingent on movement, hence a dynamic enterprise, further bolster the given answer as does a brief review of an empirical phenomenological analysis of the natural dynamic congruency of emotions and movement. In the end, the paper shows that movement and life are of a piece in the creation and appreciation of art as in everyday life.
