Visual search with animal fear-relevant stimuli: A tale of two procedures

The present study assessed preferential attentional processing of animal fear-relevant stimuli in two procedures, Search and Interference tasks, which have been suggested to reflect on attentional capture due to the fear-relevance of the stimuli presented. In the Search task, participants (N = 154) searched fear-relevant (i.e., snakes and spiders) and non fear-relevant (i.e., fish and birds) backgrounds to determine the presence or absence of a deviant animal from the opposite category. In the Interference task, the same participants searched for the presence or absence of a neutral target (a cat) when either a snake, spider or no distracter were embedded amongst backgrounds of other animal stimuli. Replicating previous findings, preferential attentional processing of animal fear-relevant stimuli was evident in both procedures and participants who specifically feared one animal but not the other showed enhanced preferential processing of their feared fear-relevant animal. However, across the entire sample, there was no relationship between self-reported levels of animal fear and preferential processing which may reflect on the fact that substantial preferential attentional processing of fear-relevant animals was evident in the entire sample. Also, preferential attentional processing as assessed in the two tasks was not related. Delayed disengagement from fear-relevant stimuli appeared to underlie performance in the search task but not in the interference task.     

The effect of induced anxiety on cognition: threat of shock enhances aversive processing in healthy individuals

Individuals with anxiety disorders demonstrate altered cognitive performance including (1) cognitive biases towards negative stimuli (affective biases) and (2) increased cognitive rigidity (e.g., impaired conflict adaptation) on affective Stroop tasks. Threat of electric shock is frequently used to induce anxiety in healthy individuals, but the extent to which this manipulation mimics the cognitive impairment seen in anxiety disorders is unclear. In this study, 31 healthy individuals completed an affective Stroop task under safe and threat-of-shock conditions. We showed that threat (1) enhanced aversive processing and abolished a positive affective bias but (2) had no effect on conflict adaptation. Threat of shock thus partially models the effects of anxiety disorders on affective Stroop tasks. We suggest that the affective state of anxiety—which is common to both threat and anxiety disorders—modulates the neural inhibition of subcortical aversive processing, whilst pathologies unique to anxiety disorders modulate conflict adaptation.     

Becoming (Hetero) Sexual? The Hetero-Spectacle of Idollators and their Real Dolls

Guys and Dolls, a BBC documentary premiering in 2007 sketches out the lives of four men in relationships with silicone-fleshed, anatomically correct Real Dolls (RDs). The men in the documentary treat their RDs as if they are alive—they dress their dolls, rub their feet, and discuss what sex and the relationship with their dolls is like. In relating with their RDs, the men respond to concerns of having “no female company” at all. In this essay, combining Stein’s (Sexualities and society: a reader, Polity Press, Oxford, pp 132–142, 2003) notion of “be-coming out,” with Deleuze and Guattari’s (A thousand plateaus: capitalism and schizophrenia, University of Minnesota Press, Minneapolis, 1987) theory of becoming, we contend that the documentary actively represents the men’s pasts in order to make sense of, justify, and construct the dynamics of their current sexual selves. Because the idollator’s be-coming narratives illuminate their heteronormative shortcomings, these sexual origin stories take a confessional tone. Although confessions regarding sexuality are not soul cleansing acts but are approval seeking performances that reify normative social boundaries, we argue for a queer reading of the Guys and Dolls text which subverts the dominant logic of heteronormativity.     

Applying a creativity framework to animal cognition

In the field of creativity, psychologists typically only study humans and biologists or ethologists usually focus either on animal problem solving or consider creativity to be an evolutionary adaptation. Yet a fuller application of creativity principles to animal behavior may both shed insight into animal cognition and expand current notions of creativity. We propose a framework for animal creativity based both on animal behavior research and creativity theories. The framework proposes different creative capabilities required for each level—i.e., one does not have to complete level 2 to reach level 3, however one does have to possess higher creative abilities. The first level is the simple ability to recognize novelty. Next is observational learning, which raises questions about imitation, intention of behavior, and the cultural transmission of creative behaviors. At the peak is creating a tool or a behavior with the specific understanding that is new and different.     

Belief bias and figural bias in syllogistic reasoning

Belief bias is the tendency to be influenced by the believability of the conclusion when attempting to solve a syllogistic reasoning problem. Figural bias is the tendency to be influenced by the order in which the information is presented in the premises when attempting to solve a syllogistic reasoning problem. When studied simultaneously they enable an investigation of whether participants' reasoning on the syllogistic reasoning task is guided by the conclusion (backward reasoning) or the premises (forward reasoning). Experiments 1 and 2 found evidence of belief bias but not figural bias on the syllogistic evaluation task paradigm. Experiments 3 and 4 found evidence of figural bias but not belief bias on the syllogistic production task paradigm. The findings highlight that different task characteristics influence performance dependent upon the nature of task presentation. These findings are discussed in the context of current theories of belief bias in syllogistic reasoning.     

Collaboration in associative recognition memory: using recalled information to defend "new" judgments

S. E. Clark, A. Hori, A. Putnam, and T. J. Martin (2000) showed that collaboration on a recognition memory task produced facilitation in recognition of targets but had inconsistent and sometimes negative effects regarding distractors. They accounted for these results within the framework of a dual-process, recall-plus-familiarity model but showed only weak evidence to support it. The present results of 3 experiments present stronger evidence for Clark et al.'s dual-process view and also show why such evidence is difficult to obtain.     

Discriminant and convergent validity of the SCL-90 in psychiatric inpatients

Examined the convergent and discriminant validity of the SCL-90 in a group of 113 psychiatric inpatients and determined the degree of reactivity to several common response sets. The nine SCL-90 dimensions were found to correlate with analogous measures from other tests, and thus showed convergent validity, but were also found to correlate with nonanalogous measures, an indication of low discriminant validity. In addition, the dimensions correlated with the three MMPI validity scales, suggesting their reactivity to response bias. These findings were interpreted as indicating that the SCL-90 has limited use with psychiatric inpatients at present, although it may be useful as a brief screening device for disposition and referral.
