Working memory in older subjects: Dealing with ongoing and stored information in language comprehension

The purpose of this experiment was to investigate the role of aging in working memory (WM), or at least the part involved in language comprehension, e.g., a double function of processing the ongoing information and keeping in memory the product of this processing. Young and older subjects were asked to simultaneously detect incongruities in sentences and keep increasing longer series of words (3, 4, or 5) in memory. The difficulty of incongruity detection was manipulated by variation of the number of intervening words (0, 6, or 12) between two critical words. Incongruity detection was assumed to be linked to the processing of information function of working memory. The concurrent mnemonic load consisted of material previously processed, and was assumed to be linked to the storage function of WM. Results showed that an increment in incongruity-detection difficulty led to a greater decrement in accuracy in older than in young subjects, indicating an impairment in the information-processing function. On the other hand, an increment in concurrent mnemonic load led to a slightly smaller decrement in accuracy in older subjects. Furthermore, fewer words from this mnemonic load were recalled in older subjects. It is suggested that older subjects are impaired in coping with both requirements of the task, and tend to sacrifice the storage of information recently processed to devote their resources to the immediate processing component of the task. These results are discussed in relation to their implications for language comprehension.

A translational comparison of contingency‐based progressive delay procedures and their effects on contextually appropriate behavior

Schedule thinning is an essential step in treating problem behavior, yet little research has been conducted to determine the method associated with sustained treatment effects. A frequently used method for thinning reinforcement is contingency‐based progressive delay, which requires the individual to meet some criteria before the reinforcers are returned. The response requirement could be dependent on (a) contextually appropriate behavior (differential reinforcement of alternative behavior‐based thinning) or (b) absence of problem behavior (differential reinforcement of other behavior‐based thinning). A translational arrangement with college students was implemented to determine the effects of these 2 response requirements. Tolerance was observed regardless of thinning method and was indicated by low rates of responding to the analogue problem behavior; however, more contextually appropriate behavior occurred during differential reinforcement of alternative behavior‐based thinning. These results support the use of response requirements for behaviors that are expected of the individual when reinforcement is not immediately forthcoming.     

The subjective quality of episodic future thought and the experience of meaning in life

Two studies assessed whether mentally simulating specific future events to occur in familiar (vs. unfamiliar) settings indirectly increases meaning life via the subjective quality of the simulations. Participants in both studies (N = 344) were randomly assigned to visualize themselves doing something in familiar (e.g. home) or unfamiliar (e.g. fantasy world) settings in the future. They then rated the subjective quality of these visualizations and completed a measure of meaning in life. We replicated previous findings by showing that mental simulations involving familiar settings were of greater subjective quality than simulations involving unfamiliar settings. However, we also found that simulating future events in familiar (vs. unfamiliar) settings indirectly increased the perceived meaningfulness of life. These findings integrate research in cognitive psychology with research on the psychology of well-being and reveal how mental time travel contributes to the perception that one’s life has meaning.     

Sex differences in adolescent ethanol drinking to behavioral intoxication

Rodent models have been especially useful for investigating adolescent ethanol exposure. However, there is a paucity of studies examining sex differences in behavioral intoxication from adolescent ethanol drinking. Here, we used an ethanol drinking model to investigate if adolescent rats of both sexes readily drink ethanol to measurable behavioral intoxication, indicated by increased impulsive action and motor incoordination. Beginning on postnatal day (P) 28, male and female Long‐Evans rats were given 30‐min access to a solution of sucrose (20%) or sweetened ethanol (20% sucrose +15% ethanol) every other day until P60 and once after 2 weeks of forced abstinence (on P75). On alternate (nondrinking) days, rats were reinforced with a food pellet for making a cued nosepoke response. Beginning on P56, rats were tested in this task after drinking sessions to assess ethanol‐induced changes in impulsive action, defined as premature responding prior to cue presentation. Motor coordination was assessed before and after drinking sessions using an incline plane test. Adolescent male and female rats readily consumed ethanol to behavioral intoxication, measured as reduced motor coordination. Following forced abstinence, females displayed greater ethanol‐induced impulsive action. These studies provide evidence for sex differences in behavioral intoxication following adolescent ethanol drinking.     

“Four Gods” in Maximum Security Prison: Images of God,Religiousness, and Worldviews Among Inmates

This paper extends research on images of God, which prior researchers based mostly on national survey data, to a study of offenders in prison. We first explore whether the distribution of Froese and Bader’s (America’s four gods: What we say about god–& what that says about us, Oxford University Press, New York 2010) four images of God among prison inmates is similar to that in the general population. We then examine whether an inmate’s image of God is associated with the inmate’s worldviews: beliefs and attitudes toward the law, other inmates, moral responsibility, and ultimate meaning and purpose in life. Finally, we test whether an inmate’s belief in a forgiving God and religiousness explain the association. We analyzed data from a survey of 2249 inmates at America’s largest maximum-security prison, the Louisiana State Penitentiary. We found the distribution of God-images among inmates was the same as that in national samples in terms of rank order. As hypothesized, we also found inmates with an image of an engaged God tended to report lower levels of legal cynicism and sense of illegitimacy of punishment and higher levels of collective efficacy, existential belief, and moral responsibility than those with images of a disengaged God or no God. Finally, we found an inmate’s belief in a forgiving God and religiousness to mediate partly relationships between images of God and the inmate’s worldviews.     

Intending,believing, and supposing at will

In this paper I consider an argument for the possibility of intending at will, and its relationship to an argument about the possibility of believing at will. I argue that although we have good reason to think we sometimes intend at will, we lack good reason to think this in the case of believing. Instead of believing at will, agents like us often suppose at will.     

Teaching social perception skills to adolescents with autism and intellectual disabilities using video‐based group instruction

Few interventions focus on teaching social skills to adolescents with autism spectrum disorder (ASD) and intellectual disabilities (ID) that are consistently used during interactions with peers ( Carter et al., 2014). The present study evaluated the effects of video‐based group instruction (VGI) on the acquisition of social perception skills of five adolescents with ASD or ID in a public school setting. Social perception involves observing affective behaviors of others, discriminating relevant environmental stimuli, and differentially reinforcing the affective behavior of another person. Typically developing peers supported VGI implementation as social partners for participants. A multiple probe design across behaviors demonstrated the effectiveness of VGI for teaching social perception skills. Four of five participants acquired and maintained the targeted social perception skills, and we observed some transfer to a nontreatment setting. Results of this study suggest VGI may support the acquisition of social perception among adolescents with ASD or ID.
