Transportability of equivalence-based programmed instruction: efficacy and efficiency in a college classroom

College students in a psychology research-methods course learned concepts related to inferential statistics and hypothesis decision making. One group received equivalence-based instruction on conditional discriminations that were expected to promote the emergence of many untaught, academically useful abilities (i.e., stimulus equivalence group). A negative control group received no instruction, and a positive (complete instruction) control group received instruction on all possible relations (those taught to, and emerging untaught in, the stimulus equivalence group). On posttests, the stimulus equivalence group performed as well as the positive control group (and both outperformed the negative control group), but those in the equivalence-based instruction condition achieved this outcome with significantly less training, thereby demonstrating the efficiency of equivalence-based instruction. Social validity measures indicated that participants found the instruction to be beneficial and as enjoyable as traditional teaching methods.     

From blooming,buzzing confusion to media literacy: The early development of television viewing

Television comprehension is a surprisingly demanding task for very young children. Based on a task analysis of television viewing and review of research, we suggest that by 6 months of age, infants can identify objects and people on screen. By 24 months they can comprehend and imitate simple actions contained in single shots and begin to integrate information across shots. Toddlers nevertheless suffer from the video deficit whereby their comprehension is less than from equivalent real life displays. During the preschool years they learn much of the grammar of filmic montage and can comprehend straightforward narrative productions. Essentially adult comprehension appears to be in place by 13 years of age.     

The role of expectation and probabilistic learning in auditory boundary perception: a model comparison

Grouping and boundary perception are central to many aspects of sensory processing in cognition. We present a comparative study of recently published computational models of boundary perception in music. In doing so, we make three contributions. First, we hypothesise a relationship between expectation and grouping in auditory perception, and introduce a novel information-theoretic model of perceptual segmentation to test the hypothesis. Although we apply the model to musical melody, it is applicable in principle to sequential grouping in other areas of cognition. Second, we address a methodological consideration in the analysis of ambiguous stimuli that produce different percepts between individuals. We propose and demonstrate a solution to this problem, based on clustering of participants prior to analysis. Third, we conduct the first comparative analysis of probabilistic-learning and rule-based models of perceptual grouping in music. In spite of having only unsupervised exposure to music, the model performs comparably to rule-based models based on expert musical knowledge, supporting a role for probabilistic learning in perceptual segmentation of music.     

Inhibitory interaction: the effects of multiple non-predictive visual cues

When the interval between a non-predictive cue and a target appearing at the same spatial location is longer than about 200 ms, target performance is typically poorer than when the cue and target appear at different locations. Recent studies have shown that this effect, known as inhibition of return (IOR), can occur at multiple cued locations, and is enhanced when multiple cues are presented at the same spatial location. However, little is known about how the magnitude of IOR at one spatial location is influenced by a subsequent or preceding cue presented at a different spatial location. We investigated this issue by presenting single or multiple cues at varying inter-cue intervals prior to target onset. Results suggest that the magnitude of IOR at a given location is influenced by the presentation of a preceding cue, but that once IOR occurs, it is unaffected by the presentation of a subsequent cue.     

Development of a Spatial Activity Questionnaire I: Items Identification

The present study aimed to develop an empirically-derived spatial activities questionnaire that would include gendered and neutral, as well as spatial and non-spatial activities. A total of 496 participants from Canada and the U.S. indicated how often they participated in 138 specific activities during their childhood. Exploratory factor analysis complemented by a multivariate analysis of variance resulted in eleven factors reflecting masculine-spatial; masculine-non- spatial; feminine-spatial; feminine-non-spatial and neutral-spatial components. Further item reduction resulted in a 27-item spatial activities questionnaire representing masculine spatial, masculine non-spatial, feminine spatial, and feminine non-spatial activities. This research constitutes the first step in the process of identifying a small set of activities that are clearly distinct in terms of their spatial nature and gender-typing.     

Sexual Priming, Gender Stereotyping, and Likelihood to Sexually Harass: Examining the Cognitive Effects of Playing a Sexually-Explicit Video Game

The present study examines the short-term cognitive effects of playing a sexually explicit video game with female “objectification” content on male players. Seventy-four male students from a university in California, U.S. participated in a laboratory experiment. They were randomly assigned to play either a sexually-explicit game or one of two control games. Participants’ cognitive accessibility to sexual and sexually objectifying thoughts was measured in a lexical decision task. A likelihood-to-sexually-harass scale was also administered. Results show that playing a video game with the theme of female “objectification” may prime thoughts related to sex, encourage men to view women as sex objects, and lead to self-reported tendencies to behave inappropriately towards women in social situations.     

Factors affecting jail detention of defendants adjudicated incompetent to proceed

The movement of defendants through the legal process who have been adjudicated incompetent to proceed is little studied, yet it is important. The purpose of this study was to provide empirical data regarding factors that affected the amount of time defendants adjudicated incompetent to proceed and ordered to undergo hospitalization remained in jail while awaiting transfer to a state hospital. Statewide data collected in Florida between July 2005 and June 2008 were used to determine the lengths of time incompetent defendants spent at certain stages in the legal process. The addition of forensic bed capacity following media attention and litigation resulted in a significant decrease in the amount of time defendants adjudicated incompetent to proceed waited in jail for transfer to a state hospital for treatment. The amount of time it took for completed commitment orders to be submitted to the state mental health authority by the Clerks of Court of each county accounted for a meaningful portion of days defendants spent in jail awaiting transfer to a state hospital, with considerable variation across counties with respect to waiting times. These findings reflect how various stakeholders can affect the amount of time defendants spend in jail while awaiting hospitalization. These issues are discussed in the context of controversy related to Florida's forensic mental health system, as well as issues related to the political process and funding of the state's mental health authority.     

"THEISTIC PSYCHOLOGY AND PSYCHOTHERAPY": A THEOLOGICAL AND SCIENTIFIC CRITIQUE

I take the APA publication A Spiritual Strategy for Counseling and Psychotherapy (Richards and Bergin 2005), along with a devoted issue of Journal of Psychology and Theology (Nelson and Slife 2006), as a paradigmatic example of a trend. Other instances include the uncritical use of "Eastern" philosophy in Humanistic and Transpersonal Psychology, almost normative appeal to the "Sacred" within the psychology of spirituality, talk of "God in the brain" within neurological research, the neologism entheogen referring to psychedelic drugs, and calls for new specializations such as neurotheology and theobiology. In response to the legitimate ethical requirements of respect and openness regarding clients' religious worldviews, the trend is to make God an essential component in psychological theory. The argument is that God is active in the universe and especially in human affairs to such an extent that any accurate account of strictly psychological matters, not just a comprehensive, interdisciplinary purview that could include a distinct theological dimension, must include God as an explanatory factor. Less nuanced than standard theological thought about divine intervention—including a range of opinions from supernaturalism, to occasionalism, to providential and deistic naturalism—this trend would blur the epistemological differences between religion and science by appeal to claimed knowledge sources such as inspiration and revelation and thus undermine the achievements of evidence-based science and establish particularistic religious beliefs as standard explanatory accounts. The concern to include a spiritual, in contrast to a religious or theist, dimension in psychological theory is welcome; but elaborated approaches, such as my own and those of Roberto Assagioli, Viktor Frankl, and Ken Wilber, open to varied theological applications, already exist.
