Testing complex animal cognition: Concept learning,proactive interference,and list memory

This article describes an approach for assessing and comparing complex cognition in rhesus monkeys and pigeons by training them in a sequence of synergistic tasks, each yielding a whole function for enhanced comparisons. These species were trained in similar same/different tasks with expanding training sets (8, 16, 32, 64, 128 … 1024 pictures) followed by novel‐stimulus transfer eventually resulting in full abstract‐concept learning. Concept‐learning functions revealed better rhesus transfer throughout and full concept learning at the 128 set, versus pigeons at the 256 set. They were then tested in delayed same/different tasks for proactive interference by inserting occasional tests within trial‐unique sessions where the test stimulus matched a previous sample stimulus (1, 2, 4, 8, 16 trials prior). Proactive‐interference functions revealed time‐based interference for pigeons (1, 10 s delays), but event‐based interference for rhesus (no effect of 1, 10, 20 s delays). They were then tested in list‐memory tasks by expanding the sample to four samples in trial‐unique sessions (minimizing proactive interference). The four‐item, list‐memory functions revealed strong recency memory at short delays, gradually changing to strong primacy memory at long delays over 30 s for rhesus, and 10 s for pigeons. Other species comparisons and future directions are discussed.     

What kind of kind is intelligence?

The model of human intelligence that is most widely adopted derives from psychometrics and behavioral genetics. This standard approach conceives intelligence as a general cognitive ability that is genetically highly heritable and describable using quantitative traits analysis. The paper analyzes intelligence within the debate on natural kinds and contends that the general intelligence conceptualization does not carve psychological nature at its joints. Moreover, I argue that this model assumes an essentialist perspective. As an alternative, I consider an HPC theory of intelligence and evaluate how it deals with essentialism and with intuitions coming from cognitive science. Finally, I highlight some concerns about the HPC model as well, and conclude by suggesting that it is unnecessary to treat intelligence as a kind in any sense.     

Patient preference as a predictor of outcomes in a pilot trial of person-centred counselling versus low-intensity cognitive behavioural therapy for persistent sub-threshold and mild depression

The aim of this analysis was to explore whether pre-treatment intervention preferences were related to outcomes for patients with persistent sub-threshold and mild depression who received one of two treatment types. Thirty-six patients took part in a two-arm, parallel group, pilot randomized controlled trial that compared short term (3 month and 6 month) outcomes of person-centred counselling (PCC) compared with low-intensity, CBT-based guided self-help (LICBT). Patient preferences for the two interventions were assessed at baseline assessment, and analysed as two independent linear variables (pro-PCC, pro-LICBT). Eight out of 30 interactions between baseline treatment preferences and treatment type were found to be significant at the p < .05 level. All were in the predicted direction, with patients who showed a stronger preference for a treatment achieving better outcomes in that treatment compared with the alternative. However, pro-LICBT was a stronger predictor of outcomes than pro-PCC. The findings provide preliminary support that treatment preferences should be taken into account when providing interventions for patients with persistent sub-threshold and mild depression. It is recommended that further research analyses preferences for different treatment types as independent variables, and examines preferences for format of treatment (e.g. guided self-help vs. face-to-face).     

The role of retributive justice and the use of international criminal tribunals in post‐conflict reconciliation

Four experiments examined people's responses to intergroup violence either committed or suffered by their own group. Experiment 1 demonstrated that Serbs who strongly glorified Serbia were more supportive of future violence against, and less willing to reconcile with, Bosniaks after reading about Serbian victimization by Bosniaks rather than Serbian transgressions against Bosniaks. Replicating these effects with Americans in the context of American–Iranian tensions, Experiment 2 further showed that demands for retributive justice explained why high glorifiers showed asymmetrical reactions to ingroup victimization vs. perpetration. Again in the Serb and the American context, respectively, Experiments 3 and 4 demonstrated that post‐conflict international criminal tribunals can help satisfy victim group members' desire for retributive justice, and thereby reduce their support for future violence and increase their willingness to reconcile with the perpetrator group. The role of retributive justice and the use of international criminal justice in intergroup conflict (reduction) are discussed.     

基于Think/No-think范式的动机性遗忘研究:行为与脑机制

想/不想范式(Think/No-think,TNT)是基于go/no-go范式提出来的用于研究动机性遗忘过程的实验范式,主要过程是指个体对于记忆的提取抑制可以导致随后该记忆的遗忘。近年来TNT范式的大量行为学研究都一致性地发现记忆提取抑制可以产生负性控制效应,验证了在实验室情境下对动机性遗忘进行研究的可行性。其中,负性控制效应指的是压抑条件的项目相对于基线条件的项目的回忆量有显著降低。关于动机性遗忘发生的神经机制的探讨已积累了大量的研究证据,总结脑电(EEG)和功能核磁共振(f MRI)两个模态的研究,我们提出了动机性遗忘发生的多模态功能网络模型。最后,在该模型的基础上,我们展望了TNT范式未来的研究方向,其中特别注意到同步EEG-f MRI技术的应用有望为我们揭示出记忆提取抑制导致的动机性遗忘发生的动态过程。     

Positive psychotherapy: A strength-based approach

Positive psychotherapy (PPT) is a therapeutic approach broadly based on the principles of positive psychology. Rooted in Chris Peterson’s groundbreaking work on character strengths, PPT integrates symptoms with strengths, resources with risks, weaknesses with values, and hopes with regrets in order to understand the inherent complexities of human experiences in a way that is more balanced than the traditional deficit-oriented approach to psychotherapy. This paper makes the case of an alternative approach to psychotherapy that pays equal attention and effort to negatives and positives. It discusses PPT’s assumptions and describes in detail how PPT exercises work in clinical settings. The paper summarizes results of pilot studies using this approach, discusses caveats in conducting PPT, and suggests potential directions.     

“AFTER THE EVENT”: FREUD'S UNCANNY AND THE ANXIETY OF ORIGINS

This essay aims to revise Freud's theory of the uncanny by rereading his own essay of that name along with the key material Freud drew on in formulating his theory: E. T. A. Hoffmann's short story “The Sandman” (1816a) and Ernst Jentsch's essay “On the Psychology of the Uncanny” (1906a). While arguing, initially, both that Jentsch's work is fundamentally misconstrued by Freud and that it offers a better account of what happens in Hoffmann's story, the essay moves beyond Jentsch's account to offer a more philosophically oriented theory of the uncanny, one more in line with Freud's ideas in Beyond the Pleasure Principle (1920a).     

Can the Same Politician Help and Hurt the Evaluations of Another Politician? The Role of Categorization on the Elicitation of Assimilation and Contrast Effects in the Mexican Political Context

Two studies investigated the effects of bringing a highly controversial politician to mind on the evaluations of another politician in the Mexican political context. We took advantage of the dynamic nature of the Mexican political context in which politicians often threaten to leave or actually leave their political parties, influencing the categorization process. We hypothesized that the same controversial politician could elicit assimilation and contrast effects on the evaluations of another politician, depending on whether both political figures were treated as lateral categories or members of the same superordinate category. Study 1 found support for the predicted contrast effects but only among those who did not classify both political figures as members of the same political party. Study 2 found support for the expected interexemplar assimilation effects but only among those who classified both political figures as members of the same political party. The theoretical and applied implications of our results were discussed.     

Re‐Presentations of Space in Hollywood Movies: An Event‐Indexing Analysis

Popular movies present chunk‐like events (scenes and subscenes) that promote episodic, serial updating of viewers’ representations of the ongoing narrative. Event‐indexing theory would suggest that the beginnings of new scenes trigger these updates, which in turn require more cognitive processing. Typically, a new movie event is signaled by an establishing shot, one providing more background information and a longer look than the average shot. Our analysis of 24 films reconfirms this. More important, we show that, when returning to a previously shown location, the re‐establishing shot reduces both context and duration while remaining greater than the average shot. In general, location shifts dominate character and time shifts in event segmentation of movies. In addition, over the last 70 years re‐establishing shots have become more like the noninitial shots of a scene. Establishing shots have also approached noninitial shot scales, but not their durations. Such results suggest that film form is evolving, perhaps to suit more rapid encoding of narrative events.     

Gray’s revised Reinforcement Sensitivity Theory in relation to Attention-Deficit/Hyperactivity and Tourette-like behaviors in the general population

Attention-Deficit/Hyperactivity Disorder (ADHD) and Tourette syndrome (TS) present as distinct conditions clinically; however, they show comorbidity and inhibitory control deficits have been proposed to underlie both. The role of reinforcement sensitivity in ADHD has been studied previously, but no study has addressed this in relation to TS-like behaviors in the general population. The present study examined these associations within the remit of the revised Reinforcement Sensitivity Theory (rRST). One hundred and thirty-eight participants completed psychometric measures of the rRST, and self-report checklists for ADHD- and TS-like behaviors. The results show that whilst ADHD-inattention was only linked to increased anxiety (BIS), ADHD-hyperactivity/impulsivity was linked to increased impulsivity (BAS-fun seeking), anxiety (BIS) and punishment sensitivity (FFFS), and to reduced reward sensitivity (BAS-reward responsiveness), independently of ‘comorbid’ TS-like behaviors. TS-related phonic tics were associated with increased BIS and FFFS, and TS-related obsessive–compulsive behaviors (OCBs) with increased goal-orientation (BAS-drive) and reduced impulsivity (BAS-fun seeking). However, these associations were driven by ADHD-like behaviors or OCB co-occurrence, respectively, suggesting little role of the rRST in pure TS-like behaviors. The results are discussed in light of mixed findings in the literature and the importance of distinguishing between multiple processing models of the rRST in distinct disorder phenotypes.
