The double-anchoring theory of lightness perception: a comment on Bressan (2006)

Recently, a double-anchoring theory (DAT) of lightness perception was proposed (P. Bressan, 2006), which offers explanations for all the data explained by the original anchoring theory (A. Gilchrist et al., 1999), as well as a number of additional lightness phenomena. Consequently, DAT can account for an unprecedented range of empirical results, potentially explaining everything from the basic simultaneous contrast display to subtle variations of the Gelb effect. In this comment, the authors raised 4 concerns that demonstrate serious theoretical and empirical difficulties for DAT.     

The power PC theory and causal powers: comment on Cheng (1997) and Novick and Cheng (2004)

It has been claimed that the power PC theory reconciles regularity and power theories of causal judgment by showing how contingency information is used for inferences about unobservable causal powers. Under the causal powers theory causal relations are understood as generative relations in which a causal power of one thing acts on a liability of another thing under some releasing condition. These 3 causal roles are implicit or explicit in all causal interpretations. The power PC theory therefore fails to reconcile power theories and regularity theories because it has a fundamentally different definition of power and does not accommodate the tripartite causal role distinction. Implications of this distinction are drawn out.     

The function of self-esteem in terror management theory and sociometer theory: comment on Pyszczynski et al. (2004)

By applying different standards of evidence to sociometer theory than to terror management theory (TMT), T. Pyszczynski, J. Greenberg, S. Solomon, J. Arndt, and J. Schimel's (2004) review offers an imbalanced appraisal of the theories' merits. Many of Pyszczynski et al.'s (2004) criticisms of sociometer theory apply equally to TMT. and others are based on misconstruals of the theory or misunderstandings regarding how people respond when rejected. Furthermore, much of their review is only indirectly relevant to TMT's position on the function of self-esteem, and the review fails to acknowledge logical and empirical challenges to TMT. A more balanced review suggests that each theory trumps the other in certain respects, both have difficulty explaining all of the evidence regarding self-esteem, and the propositions of each theory can be roughly translated into the concepts of the other. For these reasons, declaring a theoretical winner at this time is premature.     

Psychometric properties of the temperament and character inventory-revised (TCI-R) in a Belgian sample

The Temperament and Character Inventory (TCI; Cloninger, Przybeck, Svrakic, & Wetzel, 1994) is a self-questionnaire developed to assess the 7 dimensions of personality described by Cloninger et al. (1994) with a total of 29 subscales. In 1999, a revised version was proposed by Cloninger (TCI-R). In this study, we present psychometric properties of the TCI-R from 958 French-speaking participants of Belgium. Women exhibited higher scores for harm avoidance, reward dependence, and cooperativeness dimensions. The proposed factorial structure of 4 temperament dimensions and 3 character dimensions was confirmed. The TCI-R inventory had good test-retest reliabilities as well as good alpha coefficients. The addition of 3 new subscales to the original scale for Persistence has produced a very reliable dimension in the TCI-R.     

Misconceptions about Freud's seduction theory: comment on Gleaves and Hernandez (1999)

D. H. Gleaves and E. Hernandez (1999) write in relation to the seduction theory that "recent writers now argue that ... Freud never made discoveries of sexual abuse" (p. 332) and that "the assertion that Freud did not make discoveries of abuse is unwarranted" (p. 324). In this article an outline of the case that Freud had no adequate grounds for his 1896 claims of having uncovered infantile "sexual scenes" is given. Some of the more important misconceptions and erroneous arguments in Gleaves and Hernandez's article are then examined.     

A comment on Paisey and Mangan's neo-Pavlovian temperament theory and the biological bases of personality

In the course of their recent article (Paisey and Mangan, 1982) those authors suggest that the Brebner-Cooper model of extraversion cannot predict a finding by Weisen (1965) that introverts respond more often than extraverts do to avoid strong sensory stimulation. The prediction from the Brebner-Cooper model is elaborated to show how Weisen's findings are dealt with by the model.     

Short-term memory after all: comment on Sederberg, Howard, and Kahana (2008)

P. B. Sederberg, M. W. Howard, and M. J. Kahana have proposed an updated version of the temporal-context model (TCM-A). In doing so, they accepted the challenge of developing a single-store model to account for the dissociations between short- and long-term recency effects that were reviewed by E. J. Davelaar, Y. Goshen-Gottstein, A. Ashkenazi, H. J. Haarmann, and M. Usher (2005). In this commentary, the authors argue that the success of TCM-A in addressing the dissociations is dependent not only on an episodic encoding matrix but--critically--also on its implicit use of a short-term memory store--albeit exponential rather than buffer-like. The authors also highlight some difficulties of TCM-A in accounting for these dissociations, and they argue that TCM-A fails to account for critical data--the presentation-rate effect--that dissociates exponential and buffer-like models.     

The effect of inpatient cognitive-behavioral therapy for eating disorders on temperament and character

Personality traits seem to have an important role in the development, clinical expression, course, and treatment response in eating disorders (EDs). We investigated the effects of an inpatient cognitive-behavioral treatment (CBT) on the measures of temperament and character (Temperament and Character Inventory (TCI)) in 149 consecutive patients with EDs. Baseline assessment included anthropometry, the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), and the TCI. Treatment was based on the transdiagnostic cognitive behavior theory and treatment of ED, adapted for an inpatient setting. Treatment effects were tested by paired ANOVA, adjusted for covariates. No effects were found on Novelty Seeking, Reward Dependence, and Cooperativeness. Harm Avoidance (F=18.17, p<0.001), Persistence (F=7.71, p=0.006), Self-Directedness (F=27.55, p<0.001), and Self Transcendence (F=16.38, p<0.001) significantly changed after treatment. Changes in TCI scores were wholly dependent on the changes in BDI and EDE, and independent of ED diagnosis and behavior and of BMI changes. We conclude that in ED, a few scales of both temperament and character are significantly modified by CBT, in relation to changes in psychopathology and depression, independently of nutrition. These results are relevant for future studies based on TCI.     

The genetic and environmental relationship between Cloninger's dimensions of temperament and character

The purpose of this study was to determine whether Cloninger's revised 7-factor model of personality showed incremental validity over his four dimensions of temperament. A sample of 2517 Australian twins aged over 50 between 1993 and 1995 returned completed self-reported measures of Self-directedness, Cooperativeness, and Self-transcendence from Cloninger's Temperament and Character Inventory. Many of these twins had participated in a 1988 study containing Cloninger's temperament measures of Harm Avoidance, Novelty Seeking, Reward Dependence and Persistence. Contrary to theoretical expectations, univariate analyses revealed that familial aggregation for the character dimensions could be entirely explained by additive gene action alone. Although temperament explained 26, 37 and 10% of additive genetic variance in Self-directedness, Cooperativeness and Self-transcendence, respectively, seven genetic factors were required to explain the genetic variance among the TPQ dimensions, and almost all of the non-shared environmental variance was unique to each dimension of character. Our results indicate that the inclusion of all seven dimensions in a taxonomy of personality is warranted.     

Conundrums in a theory of disturbed dreaming: comment on Levin and Nielsen (2007)

Levin and Nielsen (2007) presented a review of research emphasizing dreams whose content is distressing. With some broad conclusions about factors important in the understanding of distressing dreams as a springboard, the authors offered potential explanatory mechanisms for distressing dreams that range from brain structures to personality variables, drawing heavily on findings about posttraumatic stress disorder. Though a reasonable case is made for elements of the argument, implications from one perspective are not always considered in making the argument for others, issues that follow logically from certain assertions are not discussed, and certain assumptions appear unjustified. Definitional or phenomenological presentations are not always consistent, making it difficult to determine the real nature of the variables being offered and to get a clear sense of the boundaries of the model.     

False memories and statistical decision theory: comment on Miller and Wolford (1999) and Roediger and McDermott (1999)

In an analysis of H. L. Roediger and K. B. McDermott's (1995) false-memory paradigm, M. B. Miller and G. L. Wolford (1999) argued that falsely recognized items occur because a bias toward calling such items "old" is created by their membership in a studied category. This interpretation was contested by Roediger and McDermott (1999). The authors of this article approach this issue as a statistical decision problem and observe that an explanation of false memory based on stored strengths and one based on decision process can have identical implications for data. Problems with equivalent formal models of this type can frequently be resolved by looking at the effects of other variables on the fitted estimates. The authors illustrate this analysis by examining the effects of presentation duration on the parameter estimates produced by models that instantiate the 2 explanations. Although the question remains open, the storage-based interpretation was found to be somewhat more plausible.     

Genetic and environmental structure of Cloninger's temperament and character dimensions

The multivariate genetic and environmental structure of Cloninger's Temperament and Character Inventory (TCI) was investigated in a sample of 617 pairs of adolescent and young adult twins from Japan. Additive genetic factors accounted for 22% to 49% of the variability on all TCI temperament scales. Although the theory predicts lower heritability for the character scales, all character subscales had a substantial genetic contribution, and nonshared environmental influences accounted for the remainder. Multivariate genetic analyses showed that several subscales used to define one dimension shared a common genetic basis with subscales defining others. Using the degree of shared genetic influence as the basis to rearrange the TCI subscales into new dimensions, it was possible to create genetically independent scales. The implications for personality measurement, theory, and molecular genetic research are discussed.     

Processes underlying developmental reversals in false-memory formation: comment on Brainerd, Reyna, and Ceci (2008)

C. J. Brainerd, V. F. Reyna, and S. J. Ceci (2008) reviewed compelling evidence of developmental reversals in false-memory formation (i.e., younger children exhibit lower false-memory rates than do older children and adults) and proposed that this phenomenon depends on the development of gist processing (i.e., the ability to identify and process the semantic theme of word lists, events, etc.). A full understanding of development reversals, however, cannot be achieved without further characterizing the role played by complementary or opposing processes. Suggestions for future research are made from this perspective.     

Role of the serotonin transporter gene in temperament and character

The biosocial model postulates that personality is comprised of two broad domains: temperament, which is largely due to inherited variations in specific monoamine neurotransmitter systems; and character, which arises from socioculturally learned differences in values, goals, and self-concepts and is the strongest predictor of personality disorders. The model also proposes that serotonin modulates the temperament trait of harm avoidance. We analyzed the association of temperament and character traits with the 5-HTTLPR, an inherited variation that modulates serotonin transporter gene expression, in 634 volunteer subjects. Contrary to theory, the 5-HTTLPR was most strongly associated with the character traits of cooperativeness and self-directedness. Associations with the temperament traits of reward dependence and harm avoidance were weaker and could be attributable largely to cross-correlations with the character traits and demographic variables. Psychometric analysis indicated that the serotonin transporter influences two broad areas of personality, negative affect and social disaffiliation, that are consistent across inventories but are more concisely described by the 5-factor model of personality than by the biosocial model. These results suggest that there is no fundamental mechanistic distinction between character and temperament in regard to the serotonin transporter gene, and that a single neurotransmitter can influence multiple personality traits.     

Theoretical developments in decision field theory: comment on Tsetsos, Usher, and Chater (2010)

Tsetsos, Usher, and Chater (2010) presented several criticisms of decision field theory (DFT) involving its distance function, instability under externally controlled stopping times, and lack of robustness to various multialternative choice scenarios. Here, we counter those claims with a specification of a distance function based on the indifference and dominance dimensions. Using this distance function, we show that the instability problems do not arise when using the internally controlled stopping rule. In conclusion, we argue that the predictions of DFT do not conflict with the data presented and that the model yet provides a coherent and accurate account of multialternative choice phenomena.     

The media do matter: comment on Steinberg and Monahan (2011)

Steinberg and Monahan's (2011) reanalysis of the Teen Media longitudinal survey of adolescents does not meet prevailing standards for propensity score analysis and therefore does not undermine the original conclusions of the Brown, L'Engle, Pardun, Guo, Kenneavy, and Jackson (2006) analysis. The media do matter in the sexual socialization of adolescents.     

The representational theory of phenomenal character: A phenomenological critique

According to a currently popular approach to the analysis of phenomenal character mandates that the phenomenal character of an experience is entirely determined by, and is in fact identical with, the experience’s representational content. Two underlying assumptions motivate this approach to phenomenal character: (1) that conscious experiences are diaphanous or transparent, in the sense that it is impossible to discern, via introspection, any intrinsic features of an experience of x that are not experienced as features of x; and (2) that the immediate objects of consciousness are not objects per se, but rather properties. This paper explores these assumptions, advancing the thesis that each is rejectable on phenomenological grounds.     

The intelligence of the moral intuitions: comment on Haidt (2001)

The social intuitionist model (J. Haidt, 2001) posits that fast and automatic intuitions are the primary source of moral judgments. Conscious deliberations play little causal role; they are used mostly to construct post hoc justifications for judgments that have already occurred. In this article, the authors present evidence that fast and automatic moral intuitions are actually shaped and informed by prior reasoning. More generally, there is considerable evidence from outside the laboratory that people actively engage in reasoning when faced with real-world moral dilemmas. Together, these facts limit the strong claims of the social intuitionist model concerning the irrelevance of conscious deliberation.
