Overview

Cooper’s research on ganzfeld and remote viewing methodology represents an effort to optimize experimental conditions for detecting psi phenomena by combining two established parapsychological protocols. Remote viewing (the purported ability to perceive and describe distant or hidden locations) has been studied in parapsychology for decades, but success rates have been variable. Cooper and his colleagues at the University of Northampton hypothesized that ganzfeld stimulation, a technique involving sensory attenuation through uniform visual and auditory input, might enhance remote viewing performance by reducing external distractions and promoting internal focus conducive to psi expression.

This methodological approach reflects a broader trend in parapsychology toward identifying optimal psychological and physiological states for psi detection. Rather than viewing ganzfeld and remote viewing as separate paradigms, Cooper’s work treats them as potentially complementary, the sensory attenuation of ganzfeld may create a mental state more receptive to the subtle impressions thought to characterize remote viewing perception.

Remote viewing defined

Remote viewing can be defined as “the ability to perceive and to be able to describe what would be experienced if one were at some specified distant location.”¹ Although the method can vary in practice, experimental remote viewing typically involves a protocol in which a sender visits a randomly selected target location and actively engages with the target material by attending to its features and participating in appropriate activities. Meanwhile, the receiver is led through visualization techniques, often in an ordinary waking state of consciousness, by an experimenter who guides the process.¹

The remote viewing paradigm differs from classical card-guessing experiments in that it asks participants to describe spatial or environmental information rather than identify discrete symbols. This shift toward more naturalistic target material reflects evolving assumptions about how psi phenomena might manifest, as impressionistic, spatial, or sensory information rather than as precise symbolic matches.

Ganzfeld integration with remote viewing

Cooper’s innovation was to incorporate ganzfeld stimulation into the remote viewing protocol. Ganzfeld stimulation involves sensory attenuation, the controlled reduction of patterned sensory input through techniques such as halved ping-pong balls placed over the eyes (producing uniform visual field) and white noise or pink noise delivered through headphones (producing uniform auditory input). This creates a state of reduced external sensory variation while maintaining the participant’s awareness of uniform light and sound throughout the session.

An initial exploratory experiment by Roe and Flint (2007) suggested that novice participants could successfully describe randomly selected target locations while in the ganzfeld context, but that study did not make a direct comparison with performance in a waking state.¹ Cooper and colleagues subsequently designed a series of three experiments using a counterbalanced repeated measures design to directly compare remote viewing performance in ganzfeld stimulation conditions with performance in waking conditions.

Experimental results and statistical outcomes

Across the three experiments, 110 participants completed remote viewing tasks under both ganzfeld and waking conditions. The results showed a marked difference between the two conditions. In the ganzfeld stimulation condition, participants produced 43 hits out of 110 trials (39%), yielding a highly significant positive deviation from chance expectation (sum of ranks = 225, p = .000012). By contrast, in the waking remote viewing condition, participants achieved 30 hits (27.5%), which represented only a marginal improvement over chance expectation (sum of ranks = 253, p = .034).¹

The difference in z-scores for target ratings between the two conditions approached statistical significance (t[39] = 1.86, p = .065), suggesting a trend toward superior performance in the ganzfeld condition.¹ These findings provided empirical support for the hypothesis that ganzfeld stimulation enhances remote viewing performance, at least under the experimental conditions tested.

The consistency of the effect across three separate experiments strengthened the evidence. Although there were only minor variations in design across the three experiments, the ability to combine data in a summary analysis allowed Cooper and colleagues to assess the robustness of the ganzfeld advantage. The replication across multiple experiments with different cohorts of participants reduced the likelihood that the effect was due to chance or to idiosyncratic features of a single sample.

Phenomenological correlates of performance

Beyond comparing hit rates, Cooper’s research examined the psychological and phenomenological states associated with successful psi performance. In the first experiment, participants completed Pekala’s Phenomenology of Consciousness Inventory (PCI), a multidimensional measure designed to assess subjective experience during altered states. Of the 12 sub-dimensions tested, ganzfeld performance correlated significantly with three key phenomenological features: greater absorption in subjective experience, lower arousal, and less internal dialog.¹

These correlations suggest that successful remote viewing in the ganzfeld context is associated with a particular quality of consciousness, one characterized by immersion in the task and reduced self-referential thinking or mental chatter. Absorption, in particular, has been theorized in parapsychology as a trait or state conducive to psi expression, as it may reflect a capacity to focus attention inward and to engage with subtle or ambiguous perceptual information without critical filtering.

However, the consistency of these phenomenological associations proved limited across experiments. In experiments 2 and 3, individual difference measures were replaced by assessments of transliminality, openness to experience, and dissociative experiences. These personality-level constructs showed no consistent relationship with task success.¹ In experiment 2, a significant association was found with the time sense dimension of the PCI, but in experiment 3, no PCI dimensions correlated with task performance. When data were combined across all three experiments, this pattern of inconsistency was confirmed.¹

This variability across experiments suggests that while phenomenological state during the task may influence psi performance, stable individual differences in personality traits or cognitive style may not be reliable predictors. The findings imply that the ganzfeld context itself may be sufficient to induce the necessary psychological conditions for psi expression, regardless of participants’ baseline characteristics.

Methodological implications and future directions

Cooper’s work has several methodological implications for parapsychological research. First, it demonstrates that combining established protocols (in this case, ganzfeld stimulation and remote viewing) can yield stronger effects than either protocol alone. This suggests that future research might benefit from exploring other combinations of techniques designed to optimize psi-conducive states.

Second, the emphasis on phenomenological measurement highlights the importance of assessing subjective experience alongside behavioral outcomes. Understanding which aspects of consciousness correlate with psi success may inform the design of future experiments and the selection or training of participants.

Third, the inconsistency in phenomenological correlates across experiments raises questions about the stability and generalizability of such associations. Future research might investigate whether certain phenomenological states are more reliably associated with psi performance under specific experimental conditions, or whether the relationship between consciousness and psi is more fluid and context-dependent than trait-based models suggest.

Cooper’s research also opens avenues for investigating alternative methods of inducing psi-conducive states. For instance, sensory isolation in floatation tanks has been reconsidered as a potential method for promoting psi-conducive imagery, representing another approach to manipulating sensory input and consciousness in service of psi detection.²
