A new set of 84 colored nonobjects

In this article, we present 84 nonobjects we created by using the colored object pictures from Rossion and Pourtois (2004). These nonobjects were explored on a number of measures, including object resemblance, visual complexity, and an object decision task (ODT). Object resemblance for nonobjects is a construct comparable to the “word-likeness” of phonotactically legal pseudowords. The nonobjects were rated as possible objects, showing similarity to real objects. Visual complexity ratings for objects and nonobjects were comparable. In the ODT, response times (RTs) were significantly longer for nonobjects than for real-object pictures. This RT difference is analogous to the word advantage, or lexicality effect, found in lexical decision tasks, in which responses for words are generally faster than those for nonwords. This nonobject set is freely available and has the advantage of having a companion set of real-object pictures. The nonobjects are available in color and in grayscale from brm.psychonomic-journals.org/content/supplemental.     

Genes Determine Stability and the Environment Determines Change in Cognitive Ability During 35 Years of Adulthood

ABSTRACT— Previous research has demonstrated stability of cognitive ability and marked heritability during adulthood, but questions remain about the extent to which genetic factors account for this stability. We conducted a 35-year longitudinal assessment of general cognitive ability using the Armed Forces Qualification Test administered to 7,232 male twins in early adulthood and readministered to a subset of 1,237 twins during late middle age. The proportion of variance in cognitive functioning explained by genetic factors was .49 in young adulthood and .57 in late middle age. The correlation between the two administrations was .74 with a genetic correlation of 1.0, indicating that the same genetic influences operated at both times. Genetic factors were primarily responsible for stability, and nonshared environmental factors were primarily responsible for change. The genetic factors influencing cognition may change across other eras, but the same genetic influences are operating from early adulthood to late middle age.     

Preference for Same‐ Versus Cross‐Sex Friendships1

How is preferring same‐ vs. cross‐sex friendships related to one's perceptions of these friendships? In Phase 1, college students (N = 122) listed qualities they valued in their same‐ and cross‐sex friends. In Phase 2, survey items constructed from the responses were administered to 231 students who indicated a preference for same‐ vs. cross‐sex friendship. Those who reported a preference for opposite‐sex friends rated these friendships as higher in closeness, trust, caring, having common interests, and providing narcissistic benefits, compared to those who reported a preference for same‐sex friends. Results demonstrate that gender differences often associated with close friendships are greatly attenuated and sometimes reversed when preference for same‐ vs. cross‐sex friendship is included as a moderating variable.     

Fixed Roles and Situated Actions

Two visions have shaped research and theory on gender for at least 60 years. The older vision treats the genders as distinct roles that are strongly socialized and make women and men inherently different in all circumstances. The newer one treats gender as reflecting effects of different social structural relations, and it sees women and men as capable of displaying wide-ranging and overlapping responses. We clarify the two visions by stating five tenets of each. The visions affect a scholar’s choice of research topics, what one sees when women and men interact, the meanings attached to different behaviors and attitudes, how one interprets evidence, and how to know when a research question has received a satisfactory answer.     

Wavelength Theory of Colour Strikes Back: The Return of the Physical

There have been a number of criticisms, based on visual processes, of the Australian view that colour is an objective property of the world. These criticisms have led to subjective theories about colour. These visual processes (metamers, retinex theory, opponent processes, simultaneous contrast, colour constancy, subjective colours) have been examined and it is suggested that they do not carry their supposed critical weight against an objective theory. In particular, it is argued that metamers don't occur in nature and primate colour vision evolved without metamers. Thus normal colour vision occurs without the problem of metamers. This argument, in conjunction with evidence against the critical roles of opponent processes and retinex theory in colour vision, is taken to suggest that colour can be given a photon energy/wavelengthrealism explanation. This proposal allows an account of the many microstructural bases of colour generation put forward by Nassau (1983). It is argued that neither disjunctive realism or reflectance realism are adequate objective explanations of colour.     

The influence of context‐specific and dispositional achievement goals on children's paired collaborative interaction

Background . Research has demonstrated that working collaboratively can have positive effects on children's learning. While key factors have been identified which influence the quality of these interactions, little research has addressed the influence of children's achievement goals on collaborative behaviour. Aims . This paper investigates the influence of mastery and performance goals on the nature of children's collaborative participation while playing a problem‐solving computer game with a peer. Sample . Forty‐eight primary schoolchildren aged 8–10 years were divided into two groups: those displaying strong personal goal preferences (dispositional group: N = 14) and those whose goal preferences were context‐dependent, displaying no consistent bias for either mastery or performance goals (context‐dependent: N = 34). Children were paired on the basis of same gender, year group, and goal orientation. Method . Context‐dependent pairs were assigned to either a mastery or a performance condition in which they received goal‐focused instructions. Dispositional pairs received only the instructions to collaborate given to all groups. Collaborative sessions were videotaped and interactions coded. Results . Children who were assigned mastery goals engaged in significantly more elaborated problem‐solving discussion whilst children who were assigned performance goals engaged in more executive help seeking and displayed lower levels of metacognitive control. Dispositional pairs shared some similar patterns, according to goal orientation, as context‐dependent pairs. Conclusions . Goal‐focused instructions can be used to influence the nature and quality of children's paired interactions. Instructing children towards mastery goals appears to promote a more collaborative style of interaction.     

'The power of being seen': an interpretative phenomenological analysis of how experienced counselling psychologists describe the meaning and significance of personal therapy in clinical practice

There is a widely acknowledged lack of clarity in psychotherapeutic training about the role of personal therapy in developing practitioner competence. This paper presents part of a wider ongoing qualitative study exploring the role that personal therapy plays in the clinical practice and training of experienced counselling psychologists. Results derived from an interpretative phenomenological analysis suggest that personal therapy is valued mainly as a means of enhancing reflectiveness within clinical work. Detailed examination of a subset of the data offers scope for exploring how this process may occur within therapy, and points to the potential significance of early attachment experiences in the development and amplification of participants' reflective capacities. A possible theoretical framework is proposed and implications for future research discussed.
