Age-related differences in time-based prospective memory: The role of time estimation in the clock monitoring strategy

Time-based prospective memory (TBPM) is required when it is necessary to remember to perform an action at a specific future point in time. This type of memory has been found to be particularly sensitive to ageing, probably because it requires a self-initiated response at a specific time. In this study, we sought to examine the involvement of temporal processes in the time monitoring strategy, which has been demonstrated to be a decisive factor in TBPM efficiency. We compared the performance of young and older adults in a TBPM task in which they had to press a response button every minute while categorising words. The design allowed participants to monitor time by checking a clock whenever they decided. Participants also completed a classic time-production task and several executive tasks assessing inhibition, updating and shifting processes. Our results confirm an age-related lack of accuracy in prospective memory performance, which seems to be related to a deficient strategic use of time monitoring. This could in turn be partially explained by age-related temporal deficits, as evidenced in the duration production task. These findings suggest that studies designed to investigate the age effect in TBPM tasks should consider the contribution of temporal mechanisms.     

Is face distinctiveness gender based?

Two experiments were carried out to study the role of gender category in evaluations of face distinctiveness. In Experiment 1, participants had to evaluate the distinctiveness and the femininity-masculinity of real or artificial composite faces. The composite faces were created by blending either faces of the same gender (sexed composite faces, approximating the sexed prototypes) or faces of both genders (nonsexed composite faces, approximating the face prototype). The results show that the distinctiveness ratings decreased as the number of blended faces increased. Distinctiveness and gender ratings did not covary for real faces or sexed composite faces, but they did vary for nonsexed composite faces. In Experiment 2, participants were asked to state which of two composite faces, one sexed and one nonsexed, was more distinctive. Sexed composite faces were selected less often. The results are interpreted as indicating that distinctiveness is based on sexed prototypes. Implications for face recognition models are discussed.     

Age-related changes in duration reproduction: involvement of working memory processes

The aim of the present research was to study age-related changes in duration reproduction by differentiating the working memory processes underlying this time estimation task. We compared performances of young and elderly adults in a duration reproduction task performed in simple and concurrent task conditions. Participants were also administered working memory tests to measure storage and central executive functions. Findings indicated a differential involvement of working memory storage and central executive functions in age-related differences in temporal tasks. The limited storage capacities explained age-related changes in the simple task of duration reproduction, and the dysfunctioning of central executive functions accounted for age-related changes in duration reproduction performed in a concurrent task condition, which involves greater attentional resources.     

Are We Prepared? Recommendations for Couple and Family Therapists Engaging with Young Generations on Social Media

Social media is a salient aspect of most people’s lives in the United States. Younger generations (e.g., Gen Z) are among some of the most likely to engage with social media and have mental health concerns. Mental health providers are beginning to use social media to engage with prospective clients. However, there is a lack of guidance on how to maximize the utility of social media engagement for couple and family therapists (CFTs). This paper reviews the current literature on therapists’ professional presence on social media and younger generations’ expectations around social media competency. Recommendations for how CFTs can effectively engage with younger generations through social media are provided. A discussion of professionalism, accessibility, demonstrating aligned values, branding CFT, and gaining a reputation of cost effectiveness are emphasized. Future directions for studying the phenomenon of therapists using social media to engage with an online audience are included.

     

When the smile is a cue to familiarity

The question discussed in the two following experiments concerns the effect of facial expressions on face recognition. Famous and unknown faces with neutral or smiling expression were presented for different inspection durations (15 ms vs 1000 ms). Subjects had to categorise these faces as famous or unknown (Experiment 1), or estimate their degree of familiarity on a rating scale (Experiment 2). Results showed that the smile increased ratings of familiarity for unfamiliar faces (Experiments 1 and 2) and for famous faces (Experiment 2). These data are discussed in the framework of current face-recognition models and are interpreted in terms of social value of the smile. It is proposed that the smiling bias found here acts at the level of the decision process.     

Temporal dissociation between distractors and targets: the impact of residual distractor processing on target responses

The authors manipulated the extent of distractor interference with learned, mapped responses by presenting distractors to participants (N = 16) before, simultaneously with, or after the target. Interference was significantly less when the distractor preceded the target's presentation by 200 ms than when distractor and target were presented simultaneously. Interference decreased progressively with increasing intervals. For both simultaneous and temporally separated distractor-target presentations, incongruent distractors were associated with the greatest interference, and neutral and congruent distractors interfered to a lesser degree. Distractors at fixation had a crucially greater impact on goal-directed responses to the target than did distractors at periphery. The authors discuss the findings in the context of (a) the time course of the processing of all inputs, (b) the subsequent enhancement of target-related information and responses, and (c) the inhibition of distractor-related information and responses.     

How does reward compete with goal-directed and stimulus-driven shifts of attention?

In order to behave adaptively, attention can be directed in space either voluntarily (i.e. endogenously) according to strategic goals, or involuntarily (i.e. exogenously) through reflexive capture by salient or novel events. The emotional or motivational values of stimuli can also influence attentional orienting. However, little is known about how reward-related effects compete or interact with endogenous and exogenous attention mechanisms. Here we designed a visual search paradigm in which goal-driven and stimulus-driven shifts of attention were manipulated by classic spatial cueing procedures, while an irrelevant, but previously rewarded stimulus also appeared as a distractor and hence competed with both types of spatial attention during search. Our results demonstrated that stimuli previously associated with a high monetary reward received higher attentional priority in the subsequent visual search task, even though these stimuli and reward were no longer task-relevant, mitigating the attentional orienting induced by both endogenous and exogenous cues.     

Executive functioning and processing speed in age-related differences in time estimation: a comparison of young,old, and very old adults

Age-related differences in time estimation were examined by comparing the temporal performance of young, young–old, and old–old adults, in relation to two major theories of cognitive aging: executive decline and cognitive slowing. We tested the hypothesis that processing speed and executive function are differentially involved in timing depending on the temporal task used. We also tested the assumption of greater age-related effects in time estimation in old–old participants. Participants performed two standard temporal tasks: duration production and duration reproduction. They also completed tests measuring executive function and processing speed. Findings supported the view that executive function is the best mediator of reproduction performance and inversely that processing speed is the best mediator of production performance. They also showed that young–old participants provide relatively accurate temporal judgments compared to old–old participants. These findings are discussed in terms of compensation mechanisms in aging.
