The etiology of dissociative identity disorder: Reply to Gee, Allen and Powell (2003).

Responds to a comment by T. Gee et al (see record 2003-04125-019) about the authors' original article (see record 1999-03012-003) which studied how clinicians treating dissociative identity disorder (DID) were or were not gathering and utilizing corroborative data. Results of this study show that many of the symptoms associated with DID were displayed by patients before entering therapy or prior to diagnosis. Gee et al argue that these results do not refute the sociocognitive model (a modified iatrogenesis model) of DID, but actually support it. The present authors maintain that their data did clearly contradict the iatrogenesis position. It is asserted that Gee et al's comment illustrates many important flaws of the iatrogenic DID argument, primarily that it is unscientific by virtue of being nondisconfirmable, and that it can only be maintained by adhering to false assumptions about DID and by misinterpreting data.

Should Providers of Treatment Be Regarded as a Random Factor? If It Ain't Broke, Don't "Fix" It: A Comment on Siemer and Joormann (2003).

In their criticism of B. E. Wampold and R. C. Serlin's (see record 2000-16737-003) analysis of treatment effects in nested designs, M. Siemer and J. Joormann (see record 2003-10163-009) argued that providers of services should be considered a fixed factor because typically providers are neither randomly selected from a population of providers nor randomly assigned to treatments, and statistical power to detect treatment effects is greater in the fixed than in the mixed model. The authors of the present article argue that if providers are considered fixed, conclusions about the treatment must be conditioned on the specific providers in the study, and they show that in this case generalizing beyond these providers incurs inflated Type I error rates.

Therapists as Fixed Versus Random Effects-Some Statistical and Conceptual Issues: A Comment on Siemer and Joormann (2003).

The authors disagree with M. Siemer and J. Joormann's (see record 2003-10163-009) assertion that therapist should be a fixed effect in psychotherapy treatment outcome studies. If treatment is properly standardized, therapist effects can be examined in preliminary tests and the therapist term deleted from analyses if such differences approach zero. If therapist effects are anticipated and either cannot be minimized through standardization or are specifically of interest because of the nature of the research question, the study has to be planned with adequate statistical power for including therapist as a random term. Simulation studies conducted by Siemer and Joormann confounded bias due to small sample size and inconsistent estimates. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Response to Glassgold et al. (2002).

Replies to comments by J. M. Glassgold et al (see record 2003-06066-010) on the current authors' original article (see record 2002-13988-007) which identified the ethical issues in efforts to ban reorientation therapies. Glassgold et al commented that the original article failed to represent the issues accurately and comprehensively. The current authors elaborate on the context in which their article was written and then comment on a couple of the points of criticism served by Glassgold et al.

Choosing between a rock and a hard place when data are scarce and the questions important: Reply to Hollenbeck, DeRue, and Mannor (2006).

This article replies to J. R. Hollenbeck, D. S. DeRue, and M. Mannor's comment (see record 2006-00819-001) critiquing R. S. Peterson, D. B. Smith, P. V. Martorana, and P. D. Owens's use (see record 2003-08045-002) of a large number of statistical tests in research with a small sample. Although Hollenbeck et al's point of view is valid, it paints a one-sided picture of the trade-offs inherent in empirical research when data are scarce and the questions important. This reply specifically discusses the dilemmas Peterson et al faced in conducting empirical research in a nascent area and suggests that theory development in such a situation can be well served by studies that use alternative or new methods with small samples. Theory development scholarship using small-sample research methods (e.g., case studies and Q sorting from archival sources) can be useful for stimulating ideas, theory, and research programs that can be tested with large-sample quantitative research.

Understanding source effects in ADHD rating scales: Reply to DuPaul (2003).

G. J. DuPaul (see record 2003-02033-012) offered two suggestions for additional research to understand the strong source effects reported by R. Gomez, G. L Burns, J. A. Walsh, and M. A. de Moura (see record 2003-02033-001) in attention-deficit/ hyperactivity disorder (ADHD) rating scales. The first suggestion was to determine whether the source effects represent mostly bias or accuracy. The second suggestion was to minimize source effects through the development of better ADHD rating scales. Because source effects can represent bias or accuracy, it is important to minimize the bias aspect through content validation procedures prior to attempts to determine whether source effects better reflect bias or accuracy. This comment offers various suggestions to reduce the bias in ADHD rating scales. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Assessing the Validity of Implicit Egotism: A Reply to Gallucci (2003).

B. W. Pelham, M. C. Mirenberg, and J. T. Jones (see record 2002-12744-001) argued that most people prefer stimuli that are associated with the self, a preference they called implicit egotism. In support of implicit egotism, Pelham et al presented evidence from 10 archival studies showing that people gravitate toward careers and places of residence that resemble their names or birthday numbers. M. Gallucci (see record 2003-09138-001) argued that alternate analyses of the same data provide strong evidence against implicit egotism. Whereas Gallucci was correct that Pelham et al's original analyses were flawed, their results remain significant even when more conservative tests are used. The authors also present new data in support of implicit egotism, including exhaustive studies of (a) common surnames and US city names and (b) common surnames and street names. The new studies also revealed that as sample sizes grow larger, studies are more likely to produce evidence of implicit egotism. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

On Doing Two Things at Once: IV. Necessary and Sufficient Conditions: Rejoinder to Lien, Proctor, and Ruthruff (2003).

Responds to the reply by Lien et al (see case 2003-09958-012) to the author's comments (see record 2003-08747-004) on Lien et al's (see record 2002-02027-010) article about the psychological refractory period. Four publications have demonstrated perfect timesharing of 1 simultaneous decisions. In all of these, (a) subjects were motivated to respond as quickly as possible, and with 1 exception that involved unusually extensive practice (E. Hazeltine, D. Teague, & R. B. Ivry, 2002, Experiment 4), (b) at least 1 of the 2 tasks was characterized by ideomotor (IM) compatibility, meaning that each task stimulus incorporated a component of the sensory feedback from its required response. Conclusions justified by these reports are that (a) the use of speed-stress instructions is necessary for perfect timesharing of 2 simultaneous decision tasks: (b) when both tasks are IM compatible, perfect timesharing requires little or no practice: (c) extensive practice is needed to achieve perfect timesharing when only 1 of the 2 tasks is IM compatible: and (d) very large amounts of practice can yield perfect timesharing of 2 decision tasks when neither is IM compatible.

Yes, cavalier attitudes can have pernicious consequences.

Responds to the comments by J. J. Krueger, K. D. Vohs, and R. F. Baumeister (see record 2007-19520-015) on the current authors' original article, "Do people's self-views matter? Self-concept and self-esteem in everyday life" (see record 2007-01685-002). Krueger et al brought up many points with which the current authors agree. Nevertheless, as Krueger et al noted these points of agreement, the current authors focus instead on several points of continued disagreement. In addition, the current authors comment on a few new twists that Krueger et al have added to their argument. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Evidence-based assessment of childhood mood disorders: Reply to Lee and Hunsley (2003).

Responds to a comment by C. M. Lee and J. Hunsley (see record 2003-04125-017) on the present authors' original article on advances in the diagnosis and treatment of childhood mood disorders (see record 2002-12134-002). In their comment, Lee and Hunsley took issue with a statement by the present authors advocating the use of projective tests, which are less empirically well-validated than other assessment techniques. The current authors concur with Lee and Hunsley that evidence-based techniques (where they exist) should be employed within a multidimensional, multi-informant, developmentally sensitive context. However, they also maintain that an optimal set of tools for identifying and treating childhood mood disorders has yet to be conclusively identified and that the clinician may ultimately find useful a broad array of techniques that are currently less well-validated.

Power and Measures of Effect Size in Analysis of Variance With Fixed Versus Random Nested Factors.

Ignoring a nested factor can influence the validity of statistical decisions about treatment effectiveness. Previous discussions have centered on consequences of ignoring nested factors versus treating them as random factors on Type I errors and measures of effect size (B. E. Wampold & R. C. Serlin, see record 2000-16737-003). The authors (a) discuss circumstances under which the treatment of nested provider effects as fixed as opposed to random is appropriate; (b) present 2 formulas for the correct estimation of effect sizes when nested factors are fixed; (c) present the results of Monte Carlo simulations of the consequences of treating providers as fixed versus random on effect size estimates, Type I error rates, and power; and (d) discuss implications of mistaken considerations of provider effects for the study of differential treatment effects in psychotherapy research.

Parenting in a broader context: A reply to Emery, Fincham, and Cummings (1992).

In their comment on the authors' (see record 1992-43921-001) discussion of the role of the family in child psychotherapy, R. E. Emery et al (see record 1993-14493-001) took issue with the emphasis on the mediational role of parenting practices and the importance of parenting as a focus of treatment. In response, it is emphasized that the aim was not to offer a comprehensive analysis of etiological factors in child psychopathology but rather to provide some practical research-based guidelines for child therapists. In addition, an attempt is made to clarify some areas of possible confusion, including the meaning of contextual variables, parenting as the appropriate focus of treatment, assumptions about what is meant by parenting, and differences in conceptualizations of intervention in family process.

Planting a tree while envisioning the forest--The recursive relation between theory and research: Reply to Blustein (2003).

In his comments regarding D. M. Tokar, J. R. Withrow, R. J. Hall, and B. Moradi's (see record 2002-08430-002) article, "Psychological Separation, Attachment Security, Vocational Self-Concept Crystallization, and Career Indecision: A Structural Equation Analysis," D. L. Blustein (see record 2002-08430-003) offered several useful suggestions for future research in the area of relationship variables and career development and also raised several concerns about Tokar et al's rationale for and use of structural equation modeling in testing their models. In this reply, the authors note points of agreement with Blustein and respond to comments with which they disagree. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Developmental Dynamics and Contemporary Evolutionary Psychology: Status Quo or Irreconcilable Views? Reply to Bjorklund (2003), Krebs (2003), Buss and Reeve (2003), Crawford (2003), and Tooby et al. (2003).

The authors address commentaries by D. F. Bjorklund (2003; see record 200309105-002); D. M. Buss and H. K. Reeve (2003; see record 200309105-004); C. B. Crawford (2003; see record 200309105-005); D. L. Krebs (2003; see record 2003-09105-003); and J. Tooby, L. Cosmides, and H. C. Barrett (2003; see record 2003-09105-006) on their analysis of the underlying assumptions of contemporary evolutionary psychology (R. Lickliter & H. Honeycutt, 2003; see record 200309105-001). The authors argue that evolutionary psychology currently offers no coherent framework for how to integrate genetic, environmental, and experiential factors into a theory of behavioral or cognitive phenotypes. The authors propose that this absence is due to a lack of developmental analysis in the major works of evolutionary psychology, resulting in an almost exclusive focus on adaptationist accounts of evolution by natural selection rather than a more broad-based focus on the process and products of evolution by epigenetic developmental dynamics.

We Said, She Said: A Response to Loftus (2003).

Responds to the comments by E. F. Loftus (see record 2003-07215-003) on the target articles by A. D. Yarmey (see record 2003-07215-001) and S. Porter et al (see record 2003-07215-002) which both examined the influence of memory (false memory and repressed memory) on adjudication. In Loftus' commentary on the Porter et al article, Loftus agreed with many of their conclusions concerning allegations in "he said, she said" legal cases. However, Loftus focused some criticism on their coverage of recovered memory evidence. It appears that the main difference in their perspectives was not related to the science of memory but rather was one of scientific education versus advocacy in the legal system.

Partial support from a nonreplication: Comment on Roma, Silberberg, Ruggiero, and Suomi (2006).

A purported replication by P. G. Roma, A. Silberberg, A. M. Ruggiero, and S. J. Suomi (see record 2006-03207-008) of the authors' previous study (see record 2003-08401-002) claims to contradict their finding that capuchin monkeys (Cebus apella) refuse to exchange with an experimenter if their partner receives a superior reward. Roma et al. used no exchange task, however, or any other task. Roma et al. offered frustration as explanation of their findings, yet failed to statistically prove that the effect of frustration is stronger than that of inequity. They also misrepresented the dependent measure of the authors' study. Reanalysis of the authors' own data indicated no role of frustration, that is, no effect of previous experience with a superior reward. The authors conclude that Roma et al.'s study is not a replication and does not disprove the authors' findings. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Substance use and AIDS: A reply to Fisher (1993).

Replies to the comment by D. G.

Comment on "The use and abuse of human figure drawings."

Comments on R. W. Motta et al's (see record 1994-04005-001) conclusion that the use of human figure drawings to assess intelligence is invalid. While Motta et al are generally successful in documenting the shortcomings of these tests, their literature review is not exhaustive. However, the arguments of Motta et al should be heeded because they are based on empirical data. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Modeling alphabetic retrieval: Rejoinder to Klahr (1994).

In D. Klahr's (see record 1994-24197-001) reply to J. Scharroo et al (see record 1994-24216-001), he ignored the basic critique on the hierarchy in the Klahr et al (see record 1984-05777-001) model of alphabetic retrieval. In this rejoinder, the modeling of alphabetic retrieval and the shape of response time curves with respect to the strong and weak tests and the alphabetic position effect is discussed. From discussion of these 2 points, it should be clear why Klahr did not deal with the main objections raised in Scharroo et al: (1) Klahr et al's (1983) response time curves did not show the predicted sawtooth shape and (2) there was no reason to assume an additional level (Level 1) in modeling alphabetic retrieval.
