Counselling and psychotherapy as a form of learning: some implications for practice

This paper explores counselling and psychotherapy as a form of learning. Previous experiences may create distortions in meaning-making perspectives, distortions that create templates for evaluating future experience. These templates act as barriers to being open to experience; thus there is an inability to learn from experience. The process of therapy can provide a learning milieu for the exploration and working through of these barriers, with a potential outcome of a return to learning from experience. It is suggested here that intrinsic to the learning milieu created in therapy there are elements of significant, transformative and emotional learning. Therapy is thus a reparative discourse that facilitates a return to learning from experience. A deconstruction of this concept is provided here as a way of developing the exploration of counselling and psychotherapy as a form of learning.     

Graph coloring, minimum-diameter partitioning, and the analysis of confusion matrices

It is well known that minimum-diameter partitioning of symmetric dissimilarity matrices can be framed within the context of coloring the vertices of a graph. Although confusion data are typically represented in the form of asymmetric similarity matrices, they are also amenable to a graph-coloring perspective. In this paper, we propose the integration of the minimum-diameter partitioning method with a neighborhood-based coloring approach for analyzing digraphs corresponding to confusion data. This procedure is capable of producing minimum-diameter partitions with the added desirable property that vertices with the same color have similar in-neighborhoods (i.e., directed edges entering the vertex) and out-neighborhoods (i.e., directed edges exiting the vertex) for the digraph corresponding to the minimum partition diameter.     

Explaining Jury Verdicts: Is Leniency Bias for Real?

Laboratory research suggests juries that begin deliberation with a strong majority (i.e., 2/3 or more) usually end up choosing the verdict favored by this majority, whereas those without a strong majority generally acquit or hang. We tested the robustness of these findings in the field by examining trial and deliberation correlates of jury verdicts using data from 79 criminal jury trials held in Indiana. As expected, several trial characteristics and the first-vote preference distribution were related to jury verdicts. However, there was no evidence of leniency bias—75% of those juries without a 2/3 majority on the first deliberation vote ended up convicting. Contributions of the study, limitations, and alternative explanations for the observed severity bias are discussed.     

Orientation-specific aftereffects to mentally generated lines

After staring at a pattern of tilted lines, subsequent lines appear to be tilted in the opposite direction (direct tilt aftereffect, TAE). In a previous fMRI study we have demonstrated a direct TAE solely induced by the mental imagination accompanied by adaptation of orientation-selective neurons located in the extrastriate cortex, supporting the assumption of a perception-like coding of mental images. In this study we enlarge and specify the evidence for a perception-like coding of orientation-imagination. First, we replicated the previously detected direct TAE induced by line imagination with altered design-variations to control possible perceptual task confounds. Second, we tried to induce two other orientation-specific aftereffects: indirect TAE and contrast-threshold elevation aftereffect by mental imagery. The results replicate a robust direct TAE by mental imagery and by visual stimulation, with no influence of attentional resource allocation or perceptual task confounds. We could not induce an indirect TAE, but observed a perception bias in the opposite direction of the indirect TAE. The mental imagery of lines induced no orientation-selective contrast-threshold elevation aftereffect. In general, mental imagery seems to influence visual perception, indicating that perceptual resources are used by mental imagery. However, the utilisation of visual resources seems to be somewhat different from utilisation by perception.     

A behavior-based circuit model of how outcome expectations organize learned behavior in larval Drosophila

Drosophila larvae combine a numerically simple brain, a correspondingly moderate behavioral complexity, and the availability of a rich toolbox for transgenic manipulation. This makes them attractive as a study case when trying to achieve a circuit-level understanding of behavior organization. From a series of behavioral experiments, we suggest a circuitry of chemosensory processing, odor-tastant memory trace formation, and the "decision" process to behaviorally express these memory traces--or not. The model incorporates statements about the neuronal organization of innate vs. conditioned chemosensory behavior, and the types of interaction between olfactory and gustatory pathways during the establishment as well as the behavioral expression of odor-tastant memory traces. It in particular suggests that innate olfactory behavior is responsive in nature, whereas conditioned olfactory behavior is captured better when seen as an action in pursuit of its outcome. It incorporates the available neuroanatomical and behavioral data and thus should be useful as scaffold for the ongoing investigations of the chemo-behavioral system in larval Drosophila.     

Visual crowding: a fundamental limit on conscious perception and object recognition

Crowding, the inability to recognize objects in clutter, sets a fundamental limit on conscious visual perception and object recognition throughout most of the visual field. Despite how widespread and essential it is to object recognition, reading and visually guided action, a solid operational definition of what crowding is has only recently become clear. The goal of this review is to provide a broad-based synthesis of the most recent findings in this area, to define what crowding is and is not, and to set the stage for future work that will extend our understanding of crowding well beyond low-level vision. Here we define six diagnostic criteria for what counts as crowding, and further describe factors that both escape and break crowding. All of these lead to the conclusion that crowding occurs at multiple stages in the visual hierarchy.     

The impact of task-irrelevant emotional stimuli on attention in three domains

Whether task-irrelevant emotional stimuli facilitate or disrupt attention performance may depend on a range of factors, such as emotion type, task difficulty, and stimulus duration. Few studies, however, have systematically examined the influence of these factors on attention performance. Sixty-three adults, scoring within a normative range for mood and anxiety symptoms, completed either an easy or difficult version of an attention task measuring three aspects of attention performance: alerting, orienting, and executive attention. Results showed that in the easy task only, threatening versus nonthreatening task-irrelevant emotional faces facilitated orienting regardless of stimulus duration. These effects were no longer significant during the difficult condition. When the easy and difficult conditions were examined together, duration effects emerged such that stimuli of longer durations lead to greater interference, although effects were nonlinear. Findings illustrate that threat-relevant emotional stimuli facilitate attention during tasks with low cognitive load, but underscore the importance of considering a range of task parameters. Results are discussed in the context of adaptive and maladaptive emotion-attention interactions.     

West vs. West like East vs. West? A comparison between Italian and US American context sensitivity and Fear of Isolation

Easterners tend to process information more holistically than Westerners. Kim and Markman (J Exp Soc Psychol 42(3):350–364, 2006) suggest that these differences are rooted in higher chronic levels of Fear of Isolation (FOI) for those cultures that process information more holistically. The goal of this study was to determine if these differences and their suggested cause could be found with two different Western cultures. Testing Italian (IT) and US American (US) adults, we found that IT participants processed information more holistically and had a higher chronic level of FOI than US participants; furthermore, the manipulation of FOI affected context sensitivity more for IT than for US participants. The results demonstrate that IT participants were more similar to previous research with Eastern populations than with Western populations (Kim and Markman in J Exp Soc Psychol 42(3):350–364, 2006) and indicate a within-Western culture difference for reasoning styles and support the hypothesis that this difference is due to different chronic levels of FOI.     

From glamour-oriented idolatry to achievement-oriented idolatry: A framing experiment among adolescents in Hong Kong and Shenzhen

The present study examined the framing effect of two modes of idolatry among a sample of 1095 secondary school students in Hong Kong and Shenzhen. Two experimental conditions were set up: in the glamour frame condition, subjects were exposed to frames that enhanced perfection and mystification of idols' personal or ideological characteristics; in the achievement frame condition, subjects were exposed to frames that enhanced emulation and identification of idols' pro-social behaviours or desirable dispositional traits. The experiment selected a prominent pop music and movie star well known in Chinese societies, Andy Lau, as the target idol. Subjects showed a consistently and significantly greater desire to glorify, idealize, identify with, emulate, and attach to Andy Lau in the achievement frame condition than in the glamour frame condition. The finding suggests that an achievement frame can heighten young people's adoration of an idol by emphasizing the idol's achievement processes. This suggestion is favourable to the possibility of transforming an idol into a role model for young people to learn to pursue career success.     

Perception as evidence accumulation and Bayesian inference: insights from masked priming

The authors argue that perception is Bayesian inference based on accumulation of noisy evidence and that, in masked priming, the perceptual system is tricked into treating the prime and the target as a single object. Of the 2 algorithms considered for formalizing how the evidence sampled from a prime and target is combined, only 1 was shown to be consistent with the existing data from the visual word recognition literature. This algorithm was incorporated into the Bayesian Reader model (D. Norris, 2006), and its predictions were confirmed in 3 experiments. The experiments showed that the pattern of masked priming is not a fixed function of the relations between the prime and the target but can be changed radically by changing the task from lexical decision to a same-different judgment. Implications of the Bayesian framework of masked priming for unconscious cognition and visual masking are discussed.
