Recognition of posed and genuine facial expressions of emotion in paranoid and nonparanoid schizophrenia

Most previous research reporting emotion-recognition deficits in schizophrenia has used posed facial expressions of emotion and chronic-schizophrenia patients. In contrast, the present research examined the ability of patients with acute paranoid and nonparanoid (disorganized) schizophrenia to recognize genuine as well as posed facial expressions of emotion. Evidence of an emotion-recognition deficit in schizophrenia was replicated, but only when posed facial expressions were used. For genuine expressions of emotion, the paranoid-schizophrenia group was more accurate than controls, nonparanoid-schizophrenia patients, and depressed patients. Future research clearly needs to consider the posed versus genuine nature of the emotional stimuli used and the type of schizophrenia patients examined.     

Compound fracture: the role of semantic transparency and morphological headedness

This paper explores the role of semantic transparency in the representation and processing of English compounds. We focus on the question of whether semantic transparency is best viewed as a property of the entire multimorphemic string or as a property of constituent morphemes. Accordingly, we investigated the processing of English compound nouns that were categorized in terms of the semantic transparency of each of their constituents. Fully transparent such as bedroom are those in which the meanings of each of the constituents are transparently represented in the meaning of the compound as a whole. These compounds were contrasted with compounds such as strawberry, in which only the second constituent is semantically transparent, jailbird, in which only the first constituent is transparent, and hogwash, in which neither constituent is semantically transparent. We propose that significant insights can be achieved through such analysis of the transparency of individual morphemes. The two experiments that we report present evidence that both semantically transparent compounds and semantically opaque compounds show morphological constituency. The semantic transparency of the morphological head (the second constituent in a morphologically right-headed language such as English) was found to play a significant role in overall lexical decision latencies, in patterns of decomposition, and in the effects of stimulus repetition within the experiment.     

Contrasting role morality and professional morality: implications for practice

Abstract The notion of role morality suggests individuals may adopt a different morality depending on the roles they undertake. Investigating role morality is important, since the mentality of role morality may allow agents to believe they can abdicate moral responsibility when acting in a role. This is particularly significant in the literature dealing with professional morality where professionals, because of their special status, may find themselves at odds with their best moral judgments. Here I tell four stories and draw out some distinctions. I conclude that role morality is a genuine and useful distinction. However, I suggest that the purported distinction between role morality and professional morality is over-determined. Therefore, alleged conflicts between the demands of role and profession (such as the different pressures on Pinto designers as employees and as engineers) are not conflicts between different kinds of demands, but rather conflicts arising from divergent roles that most workers will encounter regularly. Another analytical perspective is to look at moral choices at work in terms of power and the ability to bring about change. Finally, I draw the implication that we should stress moral awareness at a fairly abstract level for all employees and reinforce the moral primacy of individual choice.     

Priming guesses on a forced-recall test

The forced-recall paradigm requires participants to fill all spaces on the memory test even if they cannot remember all the list words. In the present study, the authors used that paradigm to examine the influence of implicit memory on guessing--when participants fill remaining spaces after they cannot remember list items. They measured explicit memory as the percentage of targets that participants designated as remembered from the list and implicit memory as the percentage of targets they wrote but did not designate as remembered (beyond chance level). The authors examined implicit memory on guessing with forced recall (Experiment 1), forced cued recall with younger and older adults (Experiment 2), and forced free and cued recall under a depth-of-processing manipulation (Experiment 3). They conclude that implicit memory influences guesses of targets in the forced-recall paradigm.     

Tests for cognitive mapping in Clark's nutcrackers (Nucifraga columbiana)

In these experiments, the authors examined the nature of the spatial information that Clark's nutcrackers (Nucifraga columbiana) use during navigation and whether this information is represented in the form of a cognitive map. In Experiment 1, nutcrackers were able to use distal cues to locate a small hidden goal. In Experiments 2 and 3, nutcrackers were given the opportunity to develop a map of a room by viewing local subsets of the landmarks in the room at a goal during training. During transfer tests, nutcrackers were presented with a landmark panorama that was not previously seen at the goal. Of 3 nutcrackers that had learned the relationship between distal cues and the goal, 3 were able to locate the goal during transfer, indicating they may have developed a cognitive map. Experiments 4 and 5 suggest that the simpler mechanism of vector integration may have been used by some nutcrackers during the transfer tests.     

Further examination of the treatment of multiply controlled inappropriate mealtime behavior

We systematically replicated Bachmeyer et al. (2009) by examining extinction procedures matched to each function, individually and in combination, to treat the food or liquid refusal of 4 children diagnosed with a feeding disorder whose inappropriate mealtime behavior was maintained by multiple functions (i.e., escape and attention). Previous research suggests that adding differential reinforcement to extinction procedures may result in better treatment outcomes. Therefore, we added differential reinforcement to extinction procedures matched to each function. Differential reinforcement and extinction matched only to escape or attention resulted in low rates of inappropriate mealtime behavior and high, stable levels of acceptance for only 1 child. Consistent with Bachmeyer et al., inappropriate mealtime behavior decreased, and acceptance increased for the remaining 3 children only after we matched differential reinforcement and extinction procedures to both escape and attention.     

Application of the dual-component model of working memory to ADHD:Greater secondary memory deficit despite confounded cognitive differences

The dual-component model postulates that working memory capacity consists of two dissociable components: maintenance in primary memory (PM) and retrieval from secondary memory (SM). Recent application of this model to attention-deficit/hyperactivity disorder (ADHD) has revealed that the SM component is more deficient than the PM component across both verbal and spatial modalities. The present study attempts to strengthen this conclusion by addressing two weaknesses in the previous study. First, the present study shows that the SM component continues to be more deficient than the PM component across both modalities under conditions in which (1) all participants were instructed to use the same recall strategy (resulting in the exclusion of fewer participants); and, (2) individual differences in this strategy were controlled. Second, the present study also documents a group difference in word reading efficiency that is confounded with diagnostic status and that might have influenced estimates of PM and SM capacities in the verbal modality. However, although the SM component is more deficient than the PM component in the ADHD group, the magnitude of this interaction does not vary as a function task modality. These findings are interpreted to suggest that the pattern of WM deficiencies observed are part of a causal pathway that can lead to the symptoms of ADHD, as well as to impairments in reading (and intelligence) due to overlapping cue-dependent retrieval mechanisms. These findings provide additional support for the notion that the SM component of WM is an important and neglected target for treatment.     

Just following orders? The rhetorical invocation of ‘obedience’ in Stanley Milgram's post‐experiment interviews

Recent research has begun to challenge the received idea that Milgram's ‘obedience’ experiments are demonstrations of obedience as typically understood (i.e., as social influence elicited in response to direct orders). One key warrant for explaining the studies in terms of obedience has been the post‐experiment interviews conducted with participants. The present study uses data from archived audio recordings of these interviews to highlight the extent to which participants used rhetorical strategies emphasising obedience when pressed by the interviewer to account for their behaviour. Previous research that has used these accounts as reports of underlying processes misses the extent to which they performed particular social actions in the context of their production. It is concluded that the standard social psychological version of ‘obedience’ is present in the experiments after all, but in a rather different way than is typically assumed—rather than an empirical finding, obedience is a participants' resource.
