Memory for intention-related material presented in a to-be-ignored channel

Three experiments were conducted to investigate the fate of intention-related material processed in a to-be-ignored channel. Participants were given an intention to respond to cues in a visual-processing stream while simultaneously trying to ignore information being presented in an auditory stream. Subsequent to the ongoing activity, a surprise recognition test for information presented in the to-be-ignored auditory modality was administered. As compared with comparable neutral information, corrected recognition memory for intention-related material was significantly better, depending on the type of event-based prospective memory task. These results suggest that holding certain kinds of intentions can bias attentional processes in a manner consistent with a perceptual readiness for uptake of intention-related material.     

Source monitoring is not always enhanced for valenced material

Source monitoring for valenced materials has received very little attention from researchers interested in the residual effects that emotion can have on memory. The three previous studies that examined memory for valenced material found a source-monitoring enhancement effect. By contrast, we used two different combinations of sources and found a novel, consistent source-monitoring deficit for valenced words as compared with neutral ones. In addition, this memory deficit for contextual details did not consistently covary with item memory. We assert that it is possible to obtain an effect in which heightened attention toward valenced material reduces the binding of contextual details into memory.     

Memory performance in abstinent 3,4-methylenedioxymethamphetamine (MDMA, "ecstasy") users

Research with animals and humans has suggested that acute and subacute use of 3,4-methylenedioxymethamphetamine (MDMA "ecstasy") may lead to memory impairment. However, research is limited by (1) low power due to small sample sizes, (2) the possible confound of polydrug use, and (3) the failure to consider intelligence as a covariate. The present study compared the memory performance on the Wechsler Memory Scale-III of 26 abstinent (2-wk. minimum) recreational MDMA users with 26 abstinent (2-wk. minimum) recreational polydrug users. Despite significantly greater polydrug use amongst these MDMA users, no significant group differences in memory were observed. Regression of total lifetime amount of MDMA use also did not predict memory performance after accounting for intelligence. In addition, the length of time since abstinence (at least 2 wk.) was not associated with an increase in memory performance. Greater total lifetime cocaine use, rather than total lifetime MDMA use, was significantly associated with greater decrements in General Memory and Delayed Verbal Memory performance.     

Test-induced priming of false memories

Of interest was whether prior testing of related words primes false memories in the Deese/Roediger-McDermott (DRM) paradigm. After studying lists of related words, subjects made old-new judgments about zero, three, or six related items before being tested on critical nonpresented lures. When the recognition test was self-paced, prior testing of list items led to faster false recognition judgments, but did not increase the rate of false alarms to lures from studied lists. Critically, this pattern changed when decision making at test was speeded. When forced to respond quickly—presumably precluding the use of monitoring processes—clear test-induced priming effects were observed in the rate of false memories. The results are consistent with an activation-monitoring explanation of false memories and support that retrieving veridical memories can be a source of memory error.     

Comparing older and younger adults in an event-based prospective memory paradigm containing an output monitoring component

Two experiments with younger and older adults were conducted to investigate the output-monitoring component of event-based prospective memory. In the standard form of the task, participants must remember to press a key when a certain class of items is encountered. To evaluate output monitoring, event-based cues were repeated and participants were asked to press a different key if they could remember that an earlier response was made to a particular cue. Younger adults forgot fewer of their successful responses, but displayed a distinct bias to claim that they had responded earlier when actually they had forgotten to respond. By contrast, older adults displayed this bias much less frequently. Elaborated responding to cues had the effect of improving the performance of younger, but not older adults. The results are discussed in terms of natural repetitions and omission errors that might be made in everyday prospective memory tasks.     

Accurate identification of fear facial expressions predicts prosocial behavior

The fear facial expression is a distress cue that is associated with the provision of help and prosocial behavior. Prior psychiatric studies have found deficits in the recognition of this expression by individuals with antisocial tendencies. However, no prior study has shown accuracy for recognition of fear to predict actual prosocial or antisocial behavior in an experimental setting. In 3 studies, the authors tested the prediction that individuals who recognize fear more accurately will behave more prosocially. In Study 1, participants who identified fear more accurately also donated more money and time to a victim in a classic altruism paradigm. In Studies 2 and 3, participants' ability to identify the fear expression predicted prosocial behavior in a novel task designed to control for confounding variables. In Study 3, accuracy for recognizing fear proved a better predictor of prosocial behavior than gender, mood, or scores on an empathy scale.     

Parental influence on youth propensity to join the military

The purpose of this research was to apply the Theory of Planned Behavior (TPB) in a model of youths’ career choice intentions and parents’ recommendation intentions. Specifically, a TPB model was developed for youth-parent dyads and tested with SEM to examine parental influence on youth intentions as well as behavior. Results indicated that a modified TPB model is useful for describing how youth and parent beliefs translate into enlistment intentions and pre-enlistment behavior. The strongest impact parents appeared to have on their children was through efficacy beliefs, followed by the link between parents’ attitudes and youths’ normative beliefs. Implications for recruitment and outreach efforts are discussed.     

Listening as Religious Practice (Part Two): Exploring Qualitative Data from an Empirical Study of the Cultural Habits of Music Fans

This article analyses qualitative data from responses to open questions addressed by 231 music users in a 2009–2010 survey. By coding and quantifying the data provided, the analysis enables the construction of four ‘acoustic axes’ (uplift–relax, inspiration–memory, energy–calm, joy/happiness–sad/sadness) which make direct use of respondent-initiated terminology and enable a means of mapping the activity which occurs for listeners in the affective space created in the listening process. Use of these axes in turn suggests, at a second level of analysis and interpretation, the construction of a musical–spiritual ‘social imaginary’ (Taylor), to grasp how music is used and understood by the music users themselves with respect to their self-understanding and life-commitments. It is concluded that, while music use cannot be referred to as religious, a religion or a form of spirituality in any direct or simplistic sense, there is evidence of the seriousness and intensity with which listeners make use of their listening practices in the activity of meaning-making.
