Direct perception and the predictive mind

Predictive approaches to the mind claim that perception, cognition, and action can be understood in terms of a single framework: a hierarchy of Bayesian models employing the computational strategy of predictive coding. Proponents of this view disagree, however, over the extent to which perception is direct on the predictive approach. I argue that we can resolve these disagreements by identifying three distinct notions of perceptual directness: psychological, metaphysical, and epistemological. I propose that perception is plausibly construed as psychologically indirect on the predictive approach, in the sense of being constructivist or inferential. It would be wrong to conclude from this, however, that perception is therefore indirect in a metaphysical or epistemological sense on the predictive approach. In the metaphysical case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect solutions to the metaphysical problem of perception (e.g. naïve realism, representationalism, sense datum theory). In the epistemological case, claims about the inferential properties of constructivist perceptual mechanisms are consistent with both direct and indirect approaches to the justification of perceptual belief. In this paper, I demonstrate how proponents of the predictive approach have conflated these distinct notions of perceptual directness and indirectness, and I propose alternative strategies for developing the philosophical consequences of the approach.     

A latent class analysis of self‐identified reasons for experiencing homelessness: Opportunities for prevention

Individuals experience homelessness due to a vast number of factors. Therefore, the methods used to prevent individuals from experiencing homelessness should match their diverse needs. This study utilized survey data obtained from 577 adults experiencing homelessness to identify self‐reported causes of homelessness. A latent class analysis was conducted in order to identify classes or subgroups of respondents with distinct patterns of reported causes of homelessness. A latent class analysis is a person‐centred statistical approach that is used to determine groups of individuals who share similar characteristics. Findings from this analysis identified 5 distinct classes based on individuals' responses to 19 potential vulnerabilities or events that contributed to experiencing homelessness. Individuals tended to cluster around issues associated with (a) disability or physical health issues (4%), (b) substance abuse or mental health issues (30%), (c) report major life changes (3%), (d) financial crises (7%), or (e) employment difficulties (55%). Significant group differences occurred across military veteran status, history of homelessness, depression, and health‐related quality of life. Results for these analyses suggest that individuals report notable differences in their reasons for becoming homeless and therefore require unique preventative solutions.     

Predictors of recidivism by stalkers: a nine-year follow-up of police contacts

In a subsample of a multisite stalking study (Mohandie, Meloy, McGowan, & Williams, 2006) comprising 78 offenders from one site, 77% committed new offenses within an average follow-up of 106 months (8.8 years). Over half (56%) were charged for new stalking related offenses and 33% for violent recidivism. Violent reoffending, including sexual offenses, was predicted by risk factors consistent with existing literature: younger age at first conviction, prior release failures, and criminal history. Stalking recidivism was predicted by pre-index offending scores, using the Cormier-Lang, and prior diagnosis of a mental illness. In addition, stalkers with previously diagnosed mental illness had significantly more police contacts as complainants than those without; their recidivism was also more likely to be non-violent.     

Deviant Research: Deception,Male Internet Escorts,and Response Rates

Some social scientists who study deviant groups assume that it is necessary to use deception in order to avoid the bias associated with the decision of some subjects to not participate in such studies. Selective non-participation can lead to low response rates and, thereby, adversely affect the representativeness of the sample. This study directly tests for a differential in response rates to data gathered from an e-mail request for information on male-for-male escort fees sent by a sociologist with data gathered from an e-mail that appeared to be from a potential client asking for rates. Response rates for the social science and “client” e-mails are 15% and 60%, respectively.     

"But still, it moves"

A striking example of our sensitivity to dynamic information is our ability to infer motion from still images depicted in paintings, photographs or cartoons. What are the neural mechanisms that mediate this implied motion perception? In a recent paper, Krekelberg et al. demonstrate that form cues that imply motion are integrated with real motion information, and influence perception in both humans and monkeys and the neural processing in prototypical motion areas of the monkey brain.     

Self-reported reflective functioning and father–child interactions in a sample of fathers who have used intimate partner violence

Reflective functioning (RF) has been found to be associated with mother–child interactions, but less is known about the association of fathers’ self and child-focused RF and father–child relationships.  Fathers who have histories of intimate partner violence (IPV) are known to have poor RF, which may impact their father–child interactions.  The current study was designed to examine how types of RF are associated with father–child relationships.  Pretreatment assessments and recorded, coded father–child play interactions were used to examine associations among fathers’ history of adverse childhood experiences (ACES), RF and coded father-child play interactions in a sample of 47 fathers with a history of IPV use in the last 6 months with their coparent.  Fathers’ ACES and their child's mental states (CM) were associated with father-child dyadic play interactions.  Fathers with greater ACES and higher scores on CM had the most dyadic tension and constriction during play interactions.  Those with high ACES but low CM had scores similar to those with low ACES and low CM.  These results indicate that fathers who have used IPV and have a history of significant adversity may benefit from interventions to increase their child-focused RF and further improve their interactions with their children.     

Family interactions in black, lower-class families with delinquent and nondelinquent adolescent boys

The interaction patterns of 32 black, lower-class family triads (mother-father-son), divided into two equal groups by the son's delinquency status, were assessed across self-report and observational measures of family affect, conflict, and dominance. In support of previous research with white, middle-, and lower-middle class families, the results generally indicated that families with delinquent boys were less warm and more conflictual than families with nondelinquent boys. Relative to parents of nondelinquents, parents of delinquents were more conflictual on expressive family issues than on instrumental issues. In addition, the results showed that the content of the family interaction task (expressive vs. instrumental) influenced observed patterns of intrafamily dominance. The theoretical and practical implications of these findings are discussed.
