Kathy S. Dalton, PhD is a parapsychologist whose work at the Edinburgh Koestler Parapsychology Unit (KPU) spans ganzfeld methodology, sender-receiver dynamics, psychological correlates of psi, and dream ESP protocols. The sources retrieved for this question cover four distinct lines of research, each addressed in turn below.

Experiments

Ganzfeld creativity study (1997). Dalton ran an automated ganzfeld experiment at the KPU’s Koestler Chair of Parapsychology exploring whether creativity predicted ESP performance ^[4]. The study tested four participant populations — musicians, visual artists, writers, and actors — recruited as a creative sample. Robert L. Morris was head of the Koestler Chair during this period ^[4].

Security audit of the Edinburgh automated ganzfeld system (1996). Dalton contributed directly to the development and security hardening of the KPU’s automated ganzfeld system, implementing additional security features, sensory shielding upgrades, and programming documentation ^[6]. This work was conducted in collaboration with Robert Morris, Deborah Delanoy, Dean Radin, Robin K. Taylor, and Richard Wiseman, and resulted in a published security measures paper (Dalton, Morris, Delanoy, Radin, Taylor, and Wiseman, 1996) ^[6].

Dream GESP with dynamic targets and consensus vote (1999). Co-authored with Simon J. Sherwood, this study tested whether video-clip targets and a group consensus judging procedure could produce above-chance dream ESP results ^[2]. The design drew on the Maimonides dream ESP tradition while introducing dynamic (moving video) targets and a novel consensus voting method.

Dream GESP replication (2000). Dalton led a replication of the consensus vote dream GESP paradigm, co-authored with Jessica M. Utts, Greg Novotny, Leanne Sickafoose, Jason Burrone, and Carolyn Phillips ^[1]. This extended the 1999 design to test the robustness of the consensus vote method and the negative-emotion target hypothesis.

Personality and psi experiences — NEO-PI-R analysis (1998). Co-authored with Nancy L. Zingrone and Carlos S. Alvarado, this study analyzed data collected from Edinburgh ganzfeld participants, relating their self-reported psi experiences to the Big Five personality factors as measured by the NEO-PI-R ^[3].

Predictors of ganzfeld performance (1997). A review and analysis paper synthesizing evidence on variables — sender-receiver relationship, mental discipline practice, creativity, geomagnetic activity, and gender pairings — that predict ganzfeld ESP performance ^[5].

Methodology

Automated ganzfeld system. Dalton worked within the Edinburgh KPU’s automated ganzfeld infrastructure, which used computer-controlled target selection and presentation to eliminate experimenter handling of targets during sessions. The system ran on a 33 MHz 80386DX computer with serial port hardware ^[2]. Dalton implemented additional security features and sensory shielding and upgraded the system’s programming and documentation ^[6]. Consultations with Richard Wiseman contributed to improving the security measures ^[6].

Security design philosophy. The security paper reflects a specific methodological stance: rather than attempting full radio-frequency shielding of the receiver’s room (described as expensive), the Edinburgh team opted for using senders drawn from the research team, combined with environmental monitoring, as their primary safeguard against sensory leakage ^[6]. The paper also addressed possible acoustic leakage pathways identified in earlier autoganzfeld work at PRL.

Dream ESP protocol. The 1999 and 2000 dream studies moved away from static target images toward dynamic video-clip targets, on the hypothesis that moving stimuli better match the flowing, narrative character of dream mentation ^[2]. A group consensus judging procedure was used: rather than individual ranking alone, participants as a group reached a consensus ranking of which target best matched the dream report. The 2000 replication pre-specified a binomial hit rate measure (ranks of 1 or 2 out of 4 options, MCE = .50) as the primary outcome, and a direct hit rate for negative-emotion targets as a secondary pre-specified hypothesis ^[1].

Personality assessment. In the 1997 ganzfeld creativity study, participants completed the NEO-FFT (personality) and the Torrance Tests of Creative Thinking (verbal form) prior to their ganzfeld session ^[4]. The 1998 NEO-PI-R study used the full five-factor inventory, correlating personality facets and factors to a composite Psi Index derived from self-reported psi experiences ^[3]. The authors did not correct for multiple analyses in the NEO-PI-R study but limited discussion to results with large effect sizes (Cohen’s d ≥ .80) ^[3].

Data

No structured evidence block was supplied for this question, so the figures below come directly from the numbered sources and are reported in table form for comparability. Where the surrounding text in a source is intact and the attribution unambiguous, the figure is reported; where OCR damage obscures attribution, this is noted.

Ganzfeld creativity study — overall and subgroup results ^[4]:

Correlation between z-scores and the verbal Torrance Tests of Creative Thinking was significant for musicians (rho = .358, p < .02) but nonsignificant for the group overall and for the other subgroups ^[4]. Extroversion was nonsignificant for the overall group (rho = .021) ^[4].

Dream GESP with dynamic targets — 1999 study ^[2]:

A predicted negative correlation between geomagnetic activity (global aa index) and psi success was in the predicted direction but not significant (rho = .224) ^[2].

Dream GESP replication — 2000 study ^[1]:

The pre-specified negative-emotion hypothesis was not confirmed at conventional significance, attributable in part to the small number of trials (5) ^[1]. The exploratory female-participant hypothesis was partially confirmed: one of the two female participants scored significantly above chance, the other did not ^[1].

NEO-PI-R / Big Five personality correlates ^[3]: The Psi Index (composite of self-reported psi experiences) correlated positively with openness to experience (r = .20, p = .02, one-tailed) and with the Fantasy facet (r = .22, p = .02, one-tailed). It correlated significantly with losing awareness of time (r = .16, p = .05, one-tailed) but negatively with Conscientiousness (r = −.29, p = .004, two-tailed). Being raised in an environment with a tradition of paranormal abilities (Cohen’s d = .73) and having family members with psi experiences (d = 1.05) were each significantly associated with higher Psi Index scores ^[3].

Predictors synthesis ^[5]: The 1997 review paper does not report new primary data but synthesizes hit rates across the ganzfeld creativity literature, noting that musicians consistently emerge as the high-scoring subgroup across multiple independent studies, and that geomagnetic activity, mental discipline practice, and sender-receiver relationship each show associations with ganzfeld performance in the existing literature — while acknowledging that the geomagnetic-activity relationship “is still open to debate” ^[5].

Skeptical critiques

What critics argue. The sources retrieved for this question include no published criticism attributed to a named skeptic directed specifically at Dalton’s studies. The security paper itself, however, documents an internal critical concern: the possibility of acoustic leakage between the sender’s room and the experimenter — a pathway identified in prior analysis of PRL autoganzfeld work and addressed as a design problem in the Edinburgh system ^[6]. The 1997 creativity study and the 1998 NEO-PI-R paper each acknowledge that their analyses are exploratory and involve multiple comparisons; the NEO-PI-R authors note explicitly that they did not correct for multiple analyses and restricted discussion to large effect sizes as a partial safeguard ^[3].

What the experimental data show. The 1999 dream GESP study’s geomagnetic-activity hypothesis — a directional prediction that low geomagnetic activity would correlate with higher psi scores — was not confirmed at significance despite being in the predicted direction ^[2]. The 2000 replication’s pre-specified negative-emotion target hypothesis also fell short of significance, with only five trials contributing to that test ^[1]. Individual differences within the creativity study were heterogeneous: writers and actors scored at or below the overall mean, while musicians drove the significant subgroup finding ^[4].

Analysis. The creativity-ganzfeld connection that Dalton’s 1997 study reports for the overall sample and for musicians specifically has precedent in independent work at other sites (Juilliard-based studies are discussed in ^[5]), which provides some basis for comparing the Edinburgh finding against external replications. However, the musician subgroup result, while striking (56% hit rate, ES(h) = .65), comes from 32 trials and was not the study’s sole pre-specified primary outcome. The personality and psi-experience correlates reported in the NEO-PI-R paper are acknowledged by the authors to require replication before firm conclusions can be drawn ^[3]. Independent replication of the specific consensus-vote dream GESP protocol outside the original research group is not documented in the sources retrieved for this question.
