Within‐subject analysis of a prevention strategy for problem behavior

Although decades of research on functional analysis methodology have identified common contingencies that maintain problem behavior and effective interventions, relatively little research has been conducted on strategies to prevent the initial development of problem behavior. We conducted a 2‐part case study, the purposes of which were to illustrate the use of sensitivity tests as the bases for intervention (Study 1) and subsequently to assess the efficacy of a prevention strategy using a single‐subject design (Study 2). Results showed that the sensitivity tests identified establishing operations that may set the occasion for the development of problem behavior and that interventions based on differential reinforcement prevented increases in the severity of problem behavior relative to untreated and control baselines. Benefits and limitations to this individualized approach to prevention are discussed.     

Assessing potential reinforcement-like effects of brief stimuli unrelated to food reinforcers

It is widely assumed that reinforcers are biologically relevant stimuli, or stimuli that have been associated with biologically relevant stimuli. However, brief, arbitrary stimuli have also been reported to have reinforcement-like effects, despite being unrelated to biologically relevant stimuli like food. The present study explored the potential reinforcement-like effects of brief stimuli across 5 experiments. In Experiments 1 through 4, pigeon subjects responded for food reinforcement and brief stimulus presentations in a 2-component multiple schedule. Neither baseline response rates nor resistance to change during disruption tests were systematically greater in a component with versus without brief stimulus presentations. Increasing the rate and duration of brief stimulus presentations in Experiment 4 did not reveal reinforcement-like effects when compared directly with food. In Experiment 5, pigeons chose between independent terminal links in a concurrent-chains procedure. Across conditions, varying the location, duration, and rate of brief stimulus presentations in the terminal links had no systematic effects on preference. In contrast, varying rates of food reinforcers resulted in large and reliable shifts in preference. Therefore, the present study found no systematic evidence that brief stimuli unrelated to food reliably increase response rates, resistance to change, or preference. These data demonstrate the value of systematic replication, and a behavioral momentum approach to assessing potential reinforcement-like effects.     

“Scattered In Times”

Climate change is a temporally fragmented phenomenon: the causes and effects at work are dispersed over a remarkably long time period. Climate change exceeds human ability to forecast and quantify its effects in time. This creates serious epistemic, moral, and psychological difficulties and poses challenges to generating adequate ethical responses. Augustine’s understanding of time as a measure of imagination emphasizes the way in which human beings actively shape their sense of time. He sees “looking forward” in time as a matter of spiritual vocation that collects the self out of dispersion and connects to a transgenerational collective. A notable example of how this “looking forward” may be practiced is singing the Psalms. The Augustinian “temporal imagination” links the imaginative, affective, moral, and vocational dimensions of measuring time. This offers some preliminary avenues for reimagining a sense of time responsive to climate change’s temporal fragmentation.     

Associations between violence,criminality, and cognitive control deficits among young men living in low resource communities in South Africa

Despite empirical support for “Self-control theory” in criminology, there is controversy about how self-control should be operationalized. Working within the framework of “self-control theory,” we investigated if violence and criminal behaviors are associated with nine distinct dimensions of cognitive control in a community sample of young men (n = 654) living in peri-urban townships in South Africa. Cognitive control was assessed using the Behavior Rating Inventory of Executive Function. Multivariate statistical analysis was used, to identify associations between violence and criminality, and deaggregated measures of nine distinct components of cognitive control. Fifteen percent of the sample reported recent violence, 27% had been in physical fights with family/friends in the preceding 6 months, 10% reported being arrested, 4% reported forced sexual contact, and 26% reported intimate partner violence (IPV). Controlling for substance use and sociodemographic variables, contact with the criminal justice system and violence were associated with deficits in all domains of cognitive control. Forced sexual contact was associated with behavioral dysregulation. IPV was associated with behavior dysregulation and executive control dysfunction. Future studies might utilize deaggregated measures of self-control to provide further insight into links between particular components of cognitive control and various forms of offending and violence.     

Both fearful and happy expressions interact with gaze direction by 200 ms SOA to speed attention orienting

Attention orienting towards a gazed-at location is fundamental to social attention. Whether gaze cues can interact with emotional expressions other than those signalling environmental threat to modulate this gaze cueing, and whether this integration changes over time, remains unclear. With four experiments we demonstrate that, when perceived motion inherent to dynamic displays is controlled for, gaze cueing is enhanced by both fearful and happy faces compared to neutral faces. This enhancement is seen with stimulus-onset asynchronies ranging from 200–700?ms. Thus, gaze cueing can be reliably modulated by positive expressions, albeit to a smaller degree than fearful ones, and this gaze–emotion integration impacts behaviour as early as 200?ms post-cue onset.     

The joy of Desire: Understanding Levinas’s Desire of the Other as gift

In this paper, I argue that if we understand Levinas’s Desire of the Other as gift, we can understand it as joyful—that is, as celebratory. After presenting Levinas’s conception of Desire, I consider his claim, found in Otherwise than Being, that the self is a hostage to the Other, and I contend that, paradoxical as it may seem, being a hostage to the Other is actually liberating. Then, drawing on insights Richard Kearney offers in Reimagining the Sacred, I argue for understanding Desire as a gift that is the condition of possibility for joy. If I offer hospitality to the Other, I thereby accept the gift that makes joy possible, and this joy is not egoistic but is the proper response to the gift. Finally, I ask whether Desire can be joyful in practice, given that the pure gift is an originary condition and never a historical one, and I conclude that imperfect joy remains possible. Moreover, this imperfect joy is better than any solitary enjoyment I might experience in the total absence of the Other.
