Suggested visual hallucination without hypnosis enhances activity in visual areas of the brain

This functional Magnetic Resonance Imaging (fMRI) study investigated high and low suggestible people responding to two visual hallucination suggestions with and without a hypnotic induction. Participants in the study were asked to see color while looking at a grey image, and to see shades of grey while looking at a color image. High suggestible participants reported successful alterations in color perception in both tasks, both in and out of hypnosis, and showed a small benefit if hypnosis was induced. Low suggestible people could not perform the tasks successfully with or without the hypnotic induction. The fMRI results supported the self report data, and changes in brain activity were found in a number of visual areas. The results indicate that a hypnotic induction, although having the potential to enhance the ability of high suggestible people, is not necessary for the effective alteration of color perception by suggestion.     

The emotionally intelligent ministry: why it matters

Pizarro and Salovey hypothesise that religious systems are frequently “inherently emotionally intelligent” and that religious leaders may be experts in emotional regulation due to the inherent demands of their role. Despite such assertions, to date there appears to be little exploration of Emotional Intelligence (EI) amongst religious populations. Thus, suggesting that statements such as this may be based on supposition, speculation and stereotypes rather than grounded in sound empirical evidence. In an attempt to explore EI amongst religious systems, this study examined levels of EI amongst 226 Irish clergy. Participants completed the EI Scale. Results revealed that clergy levels of EI were lower than expected and below other diverse populations previously assessed using the same instrument. The emergence of such knowledge regarding clergy EI begins to suggest that religious systems may indeed not be conclaves of emotional abilities as previously assumed. Given the relevance and the potential value of employing EI abilities within the ministry, this result is both surprising and disconcerting.     

Resource replacement and psychological well-being during unemployment: The role of family support

There is an established inverse relationship between unemployment and psychological wellbeing. However, little is known about the processes that underlie this relationship. Using latent deprivation, conservation of resources, and social capital to form a theoretical framework, this study explored the relationship between the latent benefits associated with employment, family support, and financial strain. In a sample of 174 unemployed individuals, latent benefits were shown to partially mediate the relationship between family support and psychological well-being. Additionally, this mediation was moderated by financial strain, with latent benefits being more related to psychological well-being in those with greater financial strain. These findings provide guidance in understanding how to better address the needs that contribute to psychological well-being in those who are unemployed.     

A cross-cultural study of the representation of shape: Sensitivity to generalized cone dimensions

Many of the phenomena underlying shape recognition can be derived from an assumption that the representation of simple parts can be understood in terms of independent dimensions of generalized cones, e.g., whether the axis of a cylinder is straight or curved or whether the sides are parallel or nonparallel. What enables this sensitivity? One explanation is that the representations derive from our immersion in a manufactured world of simple objects, e.g., a cylinder and a funnel, where these dimensions can be readily discerned independent of other stimulus variations. An alternative explanation is that genetic coding and/or early experience with extended contours—a characteristic of all naturally varying visual worlds—would be sufficient to develop the appropriate representations. The Himba, a seminomadic people in a remote region of Northwestern Namibia with little exposure to regular, simple artifacts, were virtually identical to western observers in representing generalized-cone dimensions of simple shapes independently. Thus immersion in a world of simple, manufactured shapes is not required for the development of a representation that specifies these dimensions independently.     

"Don't know" responding to answerable and unanswerable questions during misleading and hypnotic interviews

"Don't know" (DK) responses to interview questions are conceptually heterogeneous, and may represent uncertainty or clear statements about the contents of memory. A study examined the subjective intent of DK responses in relation to the objective status of information queried, in the context of memory distorting procedures. Participants viewed a video and responded to answerable and unanswerable questions phrased in misleading or nonmisleading formats, while hypnotized or not hypnotized. Subjective meanings of DK responses were queried, and a recognition measure assessed the contents of memory. Lower DK and accuracy rates were consistently associated with unanswerable and misleading questions. One-third of DK responses were statements that the information had no not presented. When these were recoded, accuracy estimates for answerable questions decreased and more so for hypnotized participants. These results demonstrate that DK responses convey different types of information, thus accuracy estimates in studies that permit DK responses may be misestimated. Robust risks associated with asking unanswerable questions and asking questions at all were observed. Implications for working with DK responses during interviews are discussed.     

17,000 years of depicting the junction of two smooth shapes

Competent realistic drawings preserve viewpoint-invariant shape characteristics of simple parts, such that a contour in the object that is straight or curved, for example, is depicted that way in the drawing. A more subtle invariant--a V-shaped singularity of the occluding boundary, containing a T-junction and a contour termination--is produced at the junction between articulated smooth surfaces, as with the leg joining the body of a horse. 45% of the drawings made in 2007 by individuals with only minimal art education correctly depicted such junctions, a proportion that is not reliably different from the incidence (42%) of correct depictions in a large sample of cave art made 17000 years ago. Whether a person did or did not include the invariant in their drawing, all agreed that it made for a better depiction.
