A role for ownership and authorship in the analysis of thought insertion

Philosophers are interested in the phenomenon of thought insertion because it challenges the common assumption that one can ascribe to oneself the thoughts that one can access first-personally. In the standard philosophical analysis of thought insertion, the subject owns the ‘inserted’ thought but lacks a sense of agency towards it. In this paper we want to provide an alternative analysis of the condition, according to which subjects typically lack both ownership and authorship of the ‘inserted’ thoughts. We argue that by appealing to a failure of ownership and authorship we can describe more accurately the phenomenology of thought insertion, and distinguish it from that of non-delusional beliefs that have not been deliberated about, and of other delusions of passivity. We can also start developing a more psychologically realistic account of the relation between intentionality, rationality and self knowledge in normal and abnormal cognition.

Rhyming abilities in 9-month-olds: The role of the vowel and coda explored

Nine-month-olds can respond to a change in rhyme when the conditioned head turn procedure is used [Hayes, R. A., Slater, A., & Brown, E. (2000). Infants’ ability to categorise on the basis of rhyme.Cognitive Development, 15, 405–419]. However, it is not known whether infants are detecting the change in vowel, the change in coda, or both. In Study 1, it was found that 9-month-old infants clearly attend to both the vowel and coda of the syllables presented, since they successfully categorised the syllables on the basis of both. However, infants found it harder to detect the difference when only the vowel or the coda changed than when both changed, a pattern of results that was also found in Study 2 with adults. These findings suggest that preverbal 9-month-olds parse syllables into smaller units than just onset and rime, and do so in a manner that is comparable to that of adults. The findings are discussed in relation to work demonstrating a relationship between rhyming ability and competence in word learning, reading and writing.     

Effects of suppression and appraisals on thought frequency and distress

Cognitive theories of obsessions highlight appraisals of personal significance and thought suppression in the development and maintenance of intrusive thoughts. The current study examined the role of personal significance within the context of a thought suppression paradigm. The primary aim was to examine whether suppression would have differential effects for target thoughts appraised as personally meaningful versus relatively unimportant. A blasphemous thought served as the target thought, and highly religious and nonreligious participants were recruited. Participants completed a two-interval thought suppression task; during interval 1 they were randomly assigned to suppress or not suppress the target thought and during interval 2, all participants were given “do not suppress” instructions. Suppression resulted in sustained frequency of thoughts in contrast to the decline in thought frequency observed for non-suppression. Differential effects of suppression were found across the two groups. Moreover, suppression was associated with increased negative mood and anxiety. Results suggest that suppression of personally meaningful thoughts is a counterproductive strategy.     

The effects of thought suppression on autobiographical memory recall

While it is well documented that autobiographical memory (ABM) recall is affected in Posttraumatic Stress Disorders (PTSD), less is known about the cognitive mechanisms that underlie this pattern. This paper presents two research studies which investigated the role of thought suppression in the recall of ABMs. Study 1 assessed the role of thought suppression as a correlate of ABM retrieval in an undergraduate student sample (n = 50). The results showed that higher levels of trait thought suppression were significantly correlated with faster recall of negative episodic memories as well as reduced recall of personal semantic memories. Thought suppression remained as a significant predictor of ABM recall, even when the participants' levels of depression and post-traumatic stress reactions were considered. Study 2 investigated the causal effects of thought suppression on ABM recall. 64 undergraduate students were shown a negative video clip and were asked either to suppress any thought of the video or simply to monitor their thoughts immediately thereafter. Results showed that suppression directly led to significantly enhanced negative episodic ABM recall, as well as a significantly reduced ability to recall personal semantic memories.     

Inspection time and everyday functioning: A longitudinal study

We tested whether level and/or changes in inspection time (IT) in an elderly sample (70–85 years at baseline) predicted future independence in everyday functioning, independent from chronological age. Sixty-eight participants were initially assessed on IT and cognitive abilities in 2003, reassessed on IT in 2005, and then completed the Everyday Problems Test, a test of independence in everyday living, in 2008. Controlling for age, lower fluid reasoning at baseline (Raven’s-subset) and slowing IT over 18 months independently predicted poorer everyday functioning in 2008, together accounting for one-third variance. This supports the proposition that IT has utility as a biomarker for less favourable ageing.     

Thought control strategies as mediators of trauma symptoms in young women with histories of child sexual abuse

The current retrospective study examined thought control strategies, or cognitive techniques individuals use to deal with unpleasant thoughts following stressful events, as potential mediators of adjustment in young women with histories of child sexual abuse (CSA). In a sample of 76 undergraduate women who self-reported on abuse experiences, thought control strategies, and current trauma symptoms, several key findings emerged: (i) Greater severity of the CSA event was associated with greater reported use of worry and punishment strategies and less use of social control strategies; (ii) Increased use of worry and punishment strategies following the CSA event was associated with greater levels of trauma symptoms, while increased use of social control strategies following the CSA event was associated with lower levels of trauma symptoms; and (iii) Worry, punishment, and social control strategies served as mediators between CSA severity and trauma symptoms. The results suggest that thought control strategies, specifically increased worry and punishment, and decreased social control, play a vital role in understanding adjustment after CSA. Future research should examine the roles of these cognitive control strategies as possible avenues of intervention following CSA.     

Thought suppression failures in combat PTSD: A cognitive load hypothesis

The present study investigated the relation between thought suppression of emotionally neutral content [i.e., Wegner's (1994) “white bear”], incidental traumatic thought intrusion, and skin conductance responses in combat-related Posttraumatic Stress Disorder (PTSD). Participants included service members who either: a) had PTSD following an Operation Iraqi Freedom deployment; b) were free of psychiatric diagnosis following deployment (Combat Equivalent), or c) were pre-deployed and without psychiatric diagnosis (Pre-Deployed). PTSD Service Members reported the greatest intrusion of combat thoughts during the suppression task and demonstrated a post-suppression rebound effect with a neutral thought. Non-specific skin conductance responses indicated that the suppression task was related to similar levels of increased sympathetic activity for both the PTSD and Pre-Deployed groups, whereas the Combat Equivalent group showed no increased activation during thought suppression. Intrusive traumatic thoughts combined with failures in neutral thought suppression may be a consequence of increased cognitive load in PTSD.     

Human Rights and Pluralism in CatholicSocial Thought

The essay argues that a Catholic tradition of natural law and its conception of human rights depend on the continuing life of institutions that stand apart from and sustain standards of justice independent from the modern state and its corresponding economy. Christians contribute to a defense of human rights precisely as members of their Churches, through their social and institutional presence across the globe. Catholic social thought deals with matters of human rights from within a tradition of natural law that assumes a common human end, a common good. This ecclesiological tradition of the human good is precisely what Catholics have to offer in a context of pluralism. The Church has a task of sustaining institutions where its practical rationality about human goods offers a practical alternative in a world where the self-interest of states and purely economic interests win the day.     

Systematicity redux

One of the main challenges that Jerry Fodor and Zenon Pylyshyn (Cognition 28:3–71, 1988) posed for any connectionist theory of cognitive architecture is to explain the systematicity of thought without implementing a Language of Thought (LOT) architecture. The systematicity challenge presents a dilemma: if connectionism cannot explain the systematicity of thought, then it fails to offer an adequate theory of cognitive architecture; and if it explains the systematicity of thought by implementing a LOT architecture, then it fails to offer an alternative to the LOT hypothesis. Given that thought is systematic, connectionism can offer an adequate alternative to the LOT hypothesis only if it can meet the challenge. Although some critics tried to meet the challenge, others argued that it need not be met since thought is not in fact systematic; and some claimed not to even understand the claim that thought is systematic. I do not here examine attempts to answer the challenge. Instead, I defend the challenge itself by explicating the notion of systematicity in a way that I hope makes clear that thought is indeed systematic, and so that to offer an adequate alternative to the LOT hypothesis, connectionism must meet the challenge.
