Wisdom of the social versus non-social crowd in face identification

Face identification is more accurate when people collaborate in social dyads than when they work alone (Dowsett & Burton, 2015, Br. J. Psychol., 106, 433). Identification accuracy is also increased when the responses of two people are averaged for each item to create a ‘non-social’ dyad (White, Burton, Kemp, & Jenkins, 2013, Appl. Cogn. Psychol., 27, 769; White et al., 2015, Proc. R. Soc. B Biol. Sci., 282, 20151292). Does social collaboration add to the benefits of response averaging for face identification? We compared individuals, social dyads, and non-social dyads on an unfamiliar face identity-matching test. We also simulated non-social collaborations for larger groups of people. Individuals and social dyads judged whether face image pairs depicted the same- or different identities, responding on a 5-point certainty scale. Non-social dyads were constructed by averaging the responses of paired individuals. Both social and non-social dyads were more accurate than individuals. There was no advantage for social over non-social dyads. For larger non-social groups, performance peaked at near perfection with a crowd size of eight participants. We tested three computational models of social collaboration and found that social dyad performance was predicted by the decision of the more accurate partner. We conclude that social interaction does not bolster accuracy for unfamiliar face identity matching in dyads beyond what can be achieved by averaging judgements.     

Realizing Honneth: redistribution,recognition, and global justice

The purpose of this article is to explore the potential contribution of Axel Honneth's critical theory of recognition to empirical and normative debates on global justice. I first present, very briefly, an overview of recent theories of global distributive justice. I argue that theorists of distributive justice do not pay enough attention to sources of self-respect and conditions for identity formation, and that they are blind toward the danger of harming people's sense of self even by well-intentioned redistributive policies. Honneth's theory suffers from complementary shortcomings; it is anti-technocratic but largely oblivious to the global nature of many contemporary justice claims. Given this situation, I seek to broaden the theory's scope by outlining transnational extensions of the recognition principles of love, rights and solidarity identified by Honneth. In conclusion, I show how utilizing a broadened conceptualization of the struggle for recognition allows us to better understand the changing logic of justice-oriented foreign policies.     

The effect of interstimulus interval on sequential effects in absolute identification

In absolute identification experiments, the participant is asked to identify stimuli drawn from a small set of items which differ on a single physical dimension (e.g., 10 tones which vary in frequency). Responses in these tasks show a striking pattern of sequential dependencies: The current response assimilates towards the immediately preceding stimulus but contrasts with the stimuli further back in the sequence. This pattern has been variously interpreted as resulting from confusion of items in memory, shifts in response criteria, or the action of selective attention, and these interpretations have been incorporated into competing formal models of absolute identification performance. In two experiments, we demonstrate that lengthening the time between trials increases contrast to both the previous stimulus and the stimulus two trials back. This surprising pattern of results is difficult to reconcile with the idea that sequential dependencies result from memory confusion or from criterion shifts, but is consistent with an account that emphasizes selective attention.     

The effect of blocking inter-trial interval on sequential effects in absolute identification

Sequential effects are ubiquitous in decision-making, but no more than in the absolute identification task where participants must identify stimuli from a set of items that vary on a single dimension. A number of competing explanations for these sequential effects have been proposed, and recently Matthews and Stewart [(2009a). The effect of inter-stimulus interval on sequential effects in absolute identification. The Quarterly Journal of Experimental Psychology, 62, 2014–2029] showed that manipulations of the time between decisions is useful in discriminating between these accounts. We use a Bayesian hierarchical regression model to show that inter-trial interval has an influence on behaviour when it varies across different blocks of trials, but not when it varies from trial to trial. We discuss the implications of both our and Matthews and Stewart's results on the effect of inter-trial interval for theories of sequential effects.     

Temporal dynamics of the eye–voice span and eye movement control during oral reading

The distance between eye movements and articulation during oral reading, commonly referred to as the eye–voice span, has been a classic issue of experimental reading research since Buswell (1921). To examine the influence of the span on eye movement control, synchronised recordings of eye position and speech production were obtained during fluent oral reading. The viewing of a word almost always preceded its articulation, and the interval between the onset of a word's fixation and the onset of its articulation was approximately 500 ms. The identification and articulation of a word were closely coupled, and the fixation–speech interval was regulated through immediate adjustments of word viewing duration, unless the interval was relatively long. In this case, the lag between identification and articulation was often reduced through a regression that moved the eyes back in the text. These results indicate that models of eye movement control during oral reading need to include a mechanism that maintains a close linkage between the identification and articulation of words through continuous oculomotor adjustments.     

Emotional turbulence during the ending of psychotherapy with an anorexic adolescent

In this paper I reflect on the phase of the analytic process which precedes the termination of a psychoanalysis and describe my work with an adolescent girl. Adolescents with serious eating disorders relive in a particularly violent way, in the final phase of their analysis, the catastrophic anxiety of separation and the fear of annihilation connected with this. The perception of the final date, felt to be irrevocable, reactivates in these patients the psychotic part of their personality, which tries through a phantasy of omnipotent possession (expressed through pathological projective identification) to obscure the reality of separateness and loss. It is useful with these patients to set a date for ending at least a year in advance to enable the working through of these psychotic anxieties. Clinical material illustrates how in the final year of treatment all phases of the analytic process are relived in a violent way, and how this emotional turbulence manifests id as a battle between omnipotent phantasy and an increasing insight into psychic reality.     

Keeping mother alive: psychotherapy with a teenage mother following human trafficking

The power of new traumatic events to reignite memories and the distress of traumatic experiences earlier in life is well known to psychotherapists. When the recent trauma has been extreme, the task of assisting the patient to understand their response in the light of their earlier experience can be doubly challenging. This paper describes the therapy with an adolescent girl and her infant daughter, following the girl's escape from illegal detention, physical abuse and forced prostitution, after she was trafficked to the UK from Eastern Europe. The discussion works towards developing an understanding of the emotional interchange between the mother and infant, and the influence of the mother's traumatic experiences, on that interchange. Projective identification could be seen to occur from the mother, into her daughter, in a reversal of the situation traditionally described. The function of this for the mother and the impact on the developing infant, are considered.     

Light and movement: making contact with a traumatised and embattled latency girl

This paper shows a child psychotherapist learning and developing her technique as she attempts to make contact with a child who is extremely hard to reach. It is based on the first two years of three-times-weekly intensive psychotherapy of a latency girl who had little faith in a helpful therapeutic relationship. Her defences against such a relationship were entrenched and hard to shift. In this clinical work, the psychotherapist relies on close observation and her countertransference to develop a relationship with the child, in order to begin to make sense of her non-verbal emotional experience and communication.
