Artificial grammar learning is facilitated by distributed practice: Evidence from a letter reordering task

Cognitive Processing - Previous studies have shown that distributed practice—a training strategy that is known to facilitate memory—is likely to result in greater learning than massed...     

Instrumentality boosts appreciation: helpers are more appreciated while they are useful

We propose that in social interactions, appreciation of a helper depends on that helper's instrumentality: The more motivated one is to accomplish a goal, and the more one perceives a helper as able to facilitate that goal, the more appreciation one will feel for that helper. Four experiments supported this instrumentality-boost hypothesis by showing that beneficiaries felt more appreciation of their helpers while they were receiving help toward an ongoing task than after that task was completed or after the helper was deemed no longer instrumental. This finding held for both the positive side of appreciation (gratitude) and the negative side (feelings of indebtedness) and also across a range of relationships (complete strangers, newly acquainted partners, and friends). This pattern of appreciation is counterintuitive for helpers, and so a mismatch arises between the time courses of beneficiaries' experienced appreciation and helpers' expectations of appreciation.     

The opportunity to choose enhances long-term episodic memory

ABSTRACT

Episodic memory is typically studied under conditions that treat participants as passive agents. Here we sought to explore how actively engaging in ongoing naturalistic occurrences affects long-term episodic memory. Participants viewed 40 short movie clips that depicted a protagonist that conversed with the participants. In each clip, they were either offered the chance to (supposedly) determine the clip’s continuation (active condition), or let the computer decide for them (passive condition). Participants returned either two days or one week after the experience to undergo a true/false memory test for the clips’ details and a two-alternative recognition test for the choices made. Memory performance for both groups was superior for information and choices conveyed in the active vs. passive condition. These findings suggest that the sense of actively influencing the unfolding of events is beneficial to long-term memory of the experience at large, baring potential interventions in the fields of education and cognitive enhancement.     

Resisting the temptation to compete: Self-control promotes cooperation in mixed-motive interactions

This article provides a self-control analysis of mixed-motive interactions, including 2-person social dilemmas and bargaining encounters. We propose that mixed-motive interactions pose a self-control conflict between pursuing immediate benefits through competition and pursuing long-term benefits through cooperation. As such, anticipating high (vs. low) barriers to successful outcomes triggers counteractive self-control operations that increase cooperation, so long as people believe that by doing so they can influence others to reciprocate.     

Not Just Right Experiences: Association with Obsessive Compulsive Symptoms and Sensory Over-Responsivity

Individuals with obsessive-compulsive disorder describe “not just right experiences” as a constant uncomfortable feeling of imperfection toward sensory stimuli. This study examined the relation between “not just right experiences,” obsessive-compulsive disorder and sensory over-responsivity symptoms. Sixty college students participated in the in vivo “not just right experiences” assessment. This included four tasks for which participants rated pre-task discomfort, post-task discomfort, and urge to counteract auditory, visual, and tactile stimuli. “Not just right experiences” scores significantly correlated with obsessive-compulsive disorder scores. Tactile, auditory, and visual sensory over-responsivity scores were correlated with specific “not just right experiences” scores. Sensory over-responsivity is rarely addressed in obsessive-compulsive disorder while it contributes to symptomatology and participation.     

When friends exchange negative feedback

In four studies, we document an increase in the amount of negative feedback friends and colleagues exchange as their relationship deepens. We find that both actual and perceived relationship depth increase the amount of negative feedback people seek from and provide to each other, as well as their tendency to invest in a focal (relationship or performance) goal in response to negative feedback. The amount of positive feedback on goal pursuit, by contrast, remains stable as the relationship deepens. We attribute the increase in negative feedback to the different meaning of such feedback for people in deep versus shallow relationships: only in the context of deep relationships does negative feedback signal insufficient resource investment in the focal goal, and hence close friends and colleagues seek, provide, and respond to negative feedback.     

The Role of Anticipated Emotions in the Endowment Effect

This research explored the role of anticipated negative feelings in the observed disparity between buying and selling prices for the same endowed object. We assumed that anticipated negative reactions to losses deter people from trading an endowed object and therefore psychological variables that attenuate the emotional response to negative events should further reduce the price disparity between buyers and sellers. In 3 studies, we tested whether factors that either decrease concern about negative feelings (e.g., positive mood, framing of the transaction as involving no action) or increase the anticipated negative reaction to failure to act (e.g., priming errors of omission) further eliminate the disparity between buying and selling prices. These studies provide a novel conceptualization of the endowment bias and, more generally, illustrate the role of anticipated negative feelings in decision making.     

The substitutability of external control and self-control

Three experiments offered participants the opportunity to undertake an activity that had long-term benefits but either small or large short-term costs. The experiments investigated how self-control efforts to undertake the activity are affected by real or primed externally imposed controls. Two forms of self-control were assessed: bolstering the value of the offered activity and self-imposed penalties for failure to undertake it. The results showed that greater short-term costs elicited more self-control efforts when externally imposed controls were absent and less self-control efforts when externally imposed controls were present. Both externally imposed controls and self-control efforts prevented short-term costs from affecting participants’ intention to undertake the activity. The results were interpreted as suggesting that externally imposed control and self-control are substitutable means for pursuing activities with long-term benefits and short-term costs.     

Emotional transfer in goal systems

Five experimental studies explored the phenomenon of affective transfer in goal systems. We find that affect associated with goal attainment may be transferred to means cognitively associated with such goal-events, and that factors affecting the dimensions of transfer include the magnitude of affect invested in the goal, the quality of invested affect and the strength of association between a given means and the goal-event. Accordingly, the transfer mechanism was shown to impact the magnitude of affect experienced in regard to the means in question, as well as its kind (involving, e.g., promotion-type affect or prevention-type affect), and was shown to influence the interpersonal feelings toward others perceived as helpful to the attainment of various goals.     

Attachment anxiety,intra‐group (dis)respect,actual efforts,and group donation

The current study examines attachment‐style differences in responses to inductions of group respect and disrespect. Participants completed a scale assessing attachment anxiety and avoidance, performed group tasks, and received high, average, or low respect feedback from group members. Then we assessed commitment to this group, actual effort expenditure on behalf of the group, and money donation to the group. For participants scoring relatively high on attachment anxiety, high group respect heightened group commitment and effort expenditure on behalf of the group, whereas group disrespect led to lower group commitment but to more money donation to the group and higher effort expenditure. Participants who scored relatively low on attachment anxiety were not significantly affected by group respect or disrespect. The implications of attachment theory for group dynamics were discussed.
