Life, death and (inter)subjectivity: realism and recognition in continental feminism

I begin with the assumption that a philosophically significant tension exists today in feminist philosophy of religion between those subjects who seek to become divine and those who seek their identity in mutual recognition. My critical engagement with the ambiguous assertions of Luce Irigaray seeks to demonstrate, on the one hand, that a woman needs to recognize her own identity but, on the other hand, that each subject whether male or female must struggle in relation to the other in order to maintain realism about life and death. No one can avoid the recognition that we are each given life but each of us also dies. In addition, I raise a more general, philosophical problem for analytic philosophers who attempt to read Continental philosophy of religion: how should philosophers interpret deliberately ambiguous assertions? For example, what does Irigaray mean in asserting, ‘Divinity is what we need to become free, autonomous, sovereign’? To find an answer, I turn to the distinctively French readings of the Hegelian struggle for recognition which have preoccupied Continental philosophers especially since the first half of the last century. I explore the struggle for mutual recognition between women and men who must face the reality of life and death in order to avoid the projection of their fear of mortality onto the other sex. This includes a critical look at Irigaray’s account of subjectivity and divinity. I turn to the French philosopher Michèle Le Doeuff in order to shift the focus from divinity to intersubjectivity. I conclude that taking seriously the struggle for mutual recognition between subjects forces contemporary philosophers of religion to be realist in their living and dying. With this in mind, the lesson from the Continent for philosophy of religion is that we must not stop yearning for recognition. Indeed, we must even risk our autonomy/divinity in seeking to recognize intersubjectivity.     

The effects of aging on a measure of prospective remembering using naturalistic stimuli

The aim of this study was to determine the effect of age on the noticing and memory search stages of a prospective memory task. Three groups (n=30) of older, middle‐aged, and younger persons were compared on a task using naturalistic stimuli, designed to simulate prospective remembering in everyday life. Participants were given a list of 30 instructions, each comprising an action (e.g. [Buy a hamburger]) and associated cue (e.g. [At McDonalds]). They then watched a videotape showing the view a person would have walking along a city street and attempted to recall each task when the cue appeared. The key finding was that older participants had a disproportionate reduction in recall of actions relative to cues noticed compared to both younger and middle‐aged participants. Although the older group were significantly less likely to notice cues than were the younger participants, noticing was preserved relative to memory search. The implication of this is that noticing complex and naturalistic visual cues in a shopping environment may rely primarily on automatic memory processes, whereas memory search depends on more strategic and conscious memory processes.

Too Good to Be True? Using Realism to Enhance Applicant Attraction

Research that has examined the effects of realism on pre-hire outcomes has suggested that it does not harm recruitment. We present evidence that realistic information may, under certain circumstances, increase organizational attractiveness. Participants (N = 225) evaluated one of two recruitment messages, positive only or realistic, and reported their perceptions of organizational attractiveness, source credibility, and perceptions of the challenge inherent in the job. Consistent with our hypothesis, the realistic recruitment message led to higher organizational attractiveness than the positive only message. Contrary to expectations, however, this effect appears to be mediated through perceptions of challenge in the job, rather than perceptions of source credibility.     

Fluent Reading as the Improvement of Stimulus Control: Additive Effects of Performance-Based Interventions to Repeated Reading on Students' Reading and Error Rates

The impact of adding performance-based interventions to a skill-based intervention on oral reading fluency was examined with 3 elementary students identified as having difficulty with reading. Two performance-based interventions were combined with the skill-based intervention Repeated Reading (RR) to create the three instructional packages investigated. The packages included Repeated Readings (RR), Repeated Readings with Performance Feedback (RR/FB), and Repeated Readings with Performance Feedback and Contingent Reward (RR/FB/REW). Results suggested that Repeated Reading (RR) alone led to the greatest increase in reading fluency for participants with the highest reading rates and lowest error rates at baseline. In contrast, the participant who exhibited the lowest reading rate and highest error rate benefited the most when Repeated Readings was offered in conjunction with Performance Feedback (RR/FB) or Performance Feedback plus Contingent Reward (RR/FB/RW). Implications for blending skill- and performance-based interventions to develop stimulus control over fluent reading and future research directions are discussed.

Impairments in fear conditioning in mice lacking the nNOS gene

The fear conditioning paradigm is used to investigate the roles of various genes, neurotransmitters, and substrates in the formation of fear learning related to contextual and auditory cues. In the brain, nitric oxide (NO) produced by neuronal nitric oxide synthase (nNOS) functions as a retrograde neuronal messenger that facilitates synaptic plasticity, including the late phase of long-term potentiation (LTP) and formation of long-term memory (LTM). Evidence has implicated NO signaling in synaptic plasticity and LTM formation following fear conditioning, yet little is known about the role of the nNOS gene in fear learning. Using knockout (KO) mice with targeted mutation of the nNOS gene and their wild-type (WT) counterparts, the role of NO signaling in fear conditioning was investigated. Plasma levels of the stress hormone corticosterone were measured to determine the relationship between physiological and behavioral response to fear conditioning. Contextual fear learning was severely impaired in male and female nNOS KO mice compared with WT counterparts; cued fear learning was slightly impaired in nNOS KO mice. Sex-dependent differences in both contextual and cued fear learning were not observed in either genotype. Deficits in contextual fear learning in nNOS KO mice were partially overcome by multiple trainings. A relationship between increase in plasma corticosterone levels following footshock administration and the magnitude of contextual, but not cued freezing was also observed. Results suggest that the nNOS gene contributes more to optimal contextual fear learning than to cued fear learning, and therefore, inhibition of the nNOS enzyme may ameliorate context-dependent fear response.Anxiety disorders, such as post-traumatic stress disorder (PTSD), constitute the most prevalent mental illnesses in the United States, costing nearly one-third of the country''s total health bill (Greenberg et al. 1999). The treatment of these disorders requires overcoming complications such as reluctance to seek mental health treatment and an extremely high comorbidity rate with other affective disorders, reaching 80% (Brady 1997; Solomon and Davidson 1997). Emerging evidence suggests that dysfunctions underlying acquired anxiety and PTSD include an abnormal reaction to stress, which is mediated by specific neurochemical and neuroanatomical substrates (Yehuda and McFarlane 1995; Adamec 1997). Pharmacotherapies that target neuronal signaling molecules, such as nitric oxide (NO), may play a role in the treatment of these disorders.In the brain, N-methyl-d-aspartate receptor (NMDAR) activation and calcium influx into the cell activates the neuronal nitric oxide synthase (nNOS) enzyme to produce NO, which has the role of retrograde messenger (Snyder 1992). NO is involved in memory formation and synaptic plastic events such as late-phase long-term potentiation (LTP) (Lu et al. 1999; Arancio et al. 2001; Puzzo et al. 2006). Behavioral evidence in invertebrates (Lewin and Walters 1999; Muller 2000; Kemenes et al. 2002; Matsumoto et al. 2006) and vertebrates (Medina and Izquierdo 1995; Rickard et al. 1998; Ota et al. 2008) suggest that NO has a major role in consolidation of long-term memory (LTM). Recently, studies have shown that site-specific pharmacological blockade of NO signaling in rats impairs contextual (Resstel et al. 2008) and cued (Schafe et al. 2005) fear learning. However, the role of the nNOS gene in fear conditioning has not been investigated.In the present study, fear conditioning was investigated in homozygous nNOS knockout (KO) and wild-type (WT) mice. In the fear-conditioning paradigm, the association of a footshock (unconditioned stimulus; US), with a specific context and a neutral stimulus (auditory cue) results in learned fear. Re-exposure to the conditioning context and to the previously neutral auditory cue (conditioned stimulus; CS) elicits a freezing response in the absence of the aversive US. Thus, the fear-conditioning paradigm includes both contextual and cued fear learning components, which can be measured in separate tests. Fear conditioning recruits both the amygdala (emotional cue learning) and the hippocampus (spatial/contextual learning) (Phillips and LeDoux 1992; Goosens and Maren 2004; Mei et al. 2005). The involvement of these brain regions in fear learning and anxiety has been confirmed by animal and human imaging studies (LeDoux 1998; Rauch et al. 2006).We report that nNOS KO mice showed a severe deficiency in contextual fear learning and a less marked deficit in cued fear learning compared with WT mice after a single fear-conditioning session. This deficiency was partially improved by multiple (four) fear-conditioning sessions. In addition, we observed that plasma levels of corticosterone, the primary stress hormone in rodents, are related to contextual fear learning ability.     

Capuchin monkeys (Cebus apella) respond to video images of themselves

Many studies have used mirror-image stimulation in attempts to find self-recognition in monkeys. However, very few studies have presented monkeys with video images of themselves; the present study is the first to do so with capuchin monkeys. Six tufted capuchin monkeys were individually exposed to live face-on and side-on video images of themselves (experimental Phase 1). Both video screens initially elicited considerable interest. Two adult males looked preferentially at their face-on image, whereas two adult females looked preferentially at their side-on image; the latter elicited lateral movements and head-cocking. Only males showed communicative facial expressions, which were directed towards the face-on screen. In Phase 2 monkeys discriminated between real-time, face-on images and identical images delayed by 1 s, with the adult females especially preferring real-time images. In this phase both screens elicited facial expressions, shown by all monkeys. In Phase 3 there was no evidence of discrimination between previously recorded video images of self and similar images of a familiar conspecific. Although they showed no signs of explicit self-recognition, the monkeys’ behaviour strongly suggests recognition of the correspondence between kinaesthetic information and external visual effects. In species such as humans and great apes, this type of self-awareness feeds into a system that gives rise to explicit self-recognition.     

Fear and disgust processing during repeated exposure to threat-relevant stimuli in spider phobia

Although disgust plays a significant role in the etiology of spider phobia, there remains a paucity of research examining the role of disgust in the treatment of spider phobia. Spider fearful participants (N = 46) were randomly assigned to a disgust (view vomit images) or neutral activation (view inanimate objects) condition. They were then repeatedly exposed to a videotaped tarantula, during which time their fear, disgust, and physiological levels were assessed repeatedly. Growth curve analyses indicated that repeated exposure led to significant declines in fear and disgust with no statistically significant differences between the two conditions. However, there was marginal evidence for decreased physiological arousal during repeated exposure among spider fearful participants in the disgust activation condition compared to those in the neutral condition. Reduction in disgust during exposure in the disgust activation condition remained significant after controlling for change in fear, whereas change in fear was no longer significant after controlling for change in disgust. However, the opposite pattern of relations between change in fear and disgust was observed in the neutral activation condition. Higher fear and disgust activation during exposure was also associated with higher fear and disgust responding on a subsequent behavioral task and higher spider fear and disgust at 3-month follow-up. Baseline trait disgust propensity also predicted fear and disgust parameters during repeated exposure. The implications of these findings for the role of disgust in the treatment of spider phobia are discussed.     

Early maturity of face recognition: No childhood development of holistic processing, novel face encoding, or face-space

Historically, it was believed the perceptual mechanisms involved in individuating faces developed only very slowly over the course of childhood, and that adult levels of expertise were not reached until well into adolescence. Over the last 10 years, there has been some erosion of this view by demonstrations that all adult-like behavioural properties are qualitatively present in young children and infants. Determining the age of maturity, however, requires quantitative comparison across age groups, a task made difficult by the need to disentangle development in face perception from development in all the other cognitive factors that affect task performance. Here, we argue that full quantitative maturity is reached early, by 5-7 years at the latest and possibly earlier. This is based on a comprehensive literature review of results in the 5-years-to-adult age range, with particular focus on the results of the few previous studies that are methodologically suitable for quantitative comparison of face effects across age, plus three new experiments testing development of holistic/configural processing (faces versus objects, disproportionate inversion effect), ability to encode novel faces (assessed via implicit memory) and face-space (own-age bias).
